The beacon code previously reset TSF on every configuration call, as
some of the code was not prepared to properly calculate nexttbtt based
on current TSF.

This patch adds a common function for calculating nexttbtt and moves the
TSF reset to driver start.

This should improve AP mode compatibility with various stations that
expect the TSF to not randomly jump due to hardware resets.

Commit [3469adb3: fix potential NULL pointer dereference] introduced
a check of msg_ind allocation, but omitted allocation of msg_ind->msg.
Moreover, it introduced two if statements, which looked a bit clunky.

This commit moves allocation code outside of the critical section so
there's no need to dance around mutex_unlock, and adds the missing
allocation check.

Some cards don't update the PISR properly when all SISR bits
for Tx interrupts are being cleared and as a result we get
interrupt storm. Since we handle all tx queues all together
(so we don't really use the SISR bits to do per-queue interrupt
handling), we can manualy update PISR by doing a write-to-clear
on its Tx interrupt bits.
