PCI RME32 driver code contains a few assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.

This patch is merely for coding-style fixes (except for a slight
refactoring about AutoSync rate check, only systematic conversions),
no functional changes.

snd_sb_qsound_destroy() contains the calls of removing the previously
created mixer controls, but it doesn't clear the pointers.  As
snd_sb_qsound_destroy() itself may be repeatedly called via ioctl,
this could lead to double-free potentially.

Fix it by clearing the struct fields properly afterwards.

The handling of snd_ctl_new1() and snd_ctl_add() can be sometimes
tricky, as snd_ctl_add() automatically removes the passed object at
its error path.  The recent fix addressed an overlooked issue that is
relevant with that in SB driver code, and it can be a bit more
simplified by assigning to a temporary variable, i.e. storing to the
struct field only after the creation succeeds.

A lot of code for SB drivers is in a legacy style with assignment in
if condition.  This also made harder to catch some bugs (e.g. the
commit 1c98f574 "ALSA: emu8000: Fix a use after free in
snd_emu8000_create_mixer").

This patch fixes the coding style.  All are rather simple conversions
and there should be no functional changes.
(The changes in snd_emu8000_new() for hw->res_port1, 2 and 3 are
 slightly different from the older ones, but this shouldn't matter
 much in practice.)

Add support for retrieving the mux configuration from the hardware
when the driver is initialising. Previously the ALSA controls were
initialised to a default hard-coded state instead of being initialised
to match the hardware state.

There are 2 issues on this machine, the 1st one is mic's plug/unplug
can't be detected, that is because the mic is set to manual detecting
mode, need to apply ALC255_FIXUP_XIAOMI_HEADSET_MIC to set it to auto
detecting mode. The other one is headphone's plug/unplug can't be
detected by pulseaudio, that is because the pulseaudio will use
ucm2/sof-hda-dsp on this machine, and the ucm2 only handle
'Headphone Jack', but on this machine the headphone's pincfg sets the
location to Front, then the alsa mixer name is "Front Headphone Jack"
instead of "Headphone Jack", so override the pincfg to change location
to Left.
