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.

Most wireless drivers load their firmware at interface open time, which
generally occurs after the filesystem is available. However, the ipw drivers
load their firmware at probe time because firmware is required to read the
device MAC address. When built-in, probe happens before the filesystem is
available, hence device init will only complete successfully if the user
has made special arrangements (including firmware plus a loader in the
initramfs).

Note all this in the kconfig help text for both drivers.
