compat-wireless: add sched.h on libertas/firmware.c

sched.h is required to compile users of wake_up(),
firmware.c somehow gets sched.h included on newer kernels
but on older kernels this is not happening so include
this on the file itself. This patch should and will
be sent upstream.

This fixes this compilation error:
