get_wireless_stats handler in Host AP driver was called while atomic.
However, that function will sleep in non-Master modes, and this will

scheduling while atomic--this will not show signal quality information
when called while atomic. The real fix is pending until I find out
whether get_wireless_stats is allowed to sleep or not.
