if_spi: Fix compilation warning - unused variable 'spi'

drivers/net/wireless/libertas/if_spi.c: In function ‘if_spi_init_card’:
drivers/net/wireless/libertas/if_spi.c:1035: warning: unused variable ‘spi’

The variable is used only in a macro which uses the args only for DEBUG builds.
Remove the 'spi' variable completely.

When suspending, __ieee80211_suspend() calls ieee80211_scan_cancel(),
which will only cancel sw scan. In order to cancel hw scan, the
low-level driver has to cancel it in the suspend() callback. however,
this is too late, as a new scan_work will be enqueued (while the driver
is going into suspend).

Add a new cancel_hw_scan() callback, asking the driver to cancel an
active hw scan, and call it in ieee80211_scan_cancel().

Trigger connection monitor on resume from suspend.  Since we

The ucode subtypes keep changing, and there's no
particular reason to be checking them (other than
a paranoid sanity check). Since the numbers are
also in conflict between different ucode images
now, simply don't check them any more and rely on
the images being built correctly.

Also, to indicate that, rename the constants and
the enum, moving it to a different file.

At http://dev.laptop.org/ticket/10748 we are seeing a case of the
libertas firmware randomly stopping responding to commands after
resume. Careful monitoring of communications indicates a firmware or
hardware bug, which has been reported to Marvell.

Work around this issue by adding a reset_card method; this is
automatically called when command timeouts are detected and provides an
instant recovery to this situation.

Function ieee80211_reconfig in net/mac80211/util.c contains label wake_up
which is defined unconditionally, but only used with CONFIG_PM. Gcc
warns about this when CONFIG_PM is not defined.

This patch makes the label's definition dependent on CONFIG_PM too,
eliminating the warning.

The issue was apparently introduced in git commit
