When print_mac() was marked as __pure to avoid emitting a function
call in pr_debug() scenarios, a warning in this code surfaced since
it relies on the fact that the buffer is modified and doesn't use
the return value. This patch makes it use the return value instead.

When a STA structure is added, it is often checked whether it
already exists before adding it. This, however, isn't done
atomically so there is a race condition that could lead to two
STA structures being added with the same MAC address. This
patch changes sta_info_add() to return an ERR_PTR in case
of failure and adds the failure mode -EEXIST when the STA
already exists.

The TIM flag that is kept in each station's info is completely

Drivers should be allowed to simply get a complete new beacon when
set_tim() is invoked (and set_tim() is required for drivers that
just want a beacon template!), so we need to update our own TIM
bitmap before calling set_tim() so that getting the beacon will
now get an already updated beacon.

The async vendor requests are a ugly hack which is not working correctly.
The proper fix for the scheduling while atomic issue is finding out why
we can't use led classes for USB drivers and fix that.

Just replace all async calls with the regular ones and print an
error for the disallowed LED configuration attempts. That will
help in determining which led class is causing the problem.
