wl12xx: Reorder data handling in irq_work 

The FW has a limited amount of memory for holding frames. In case it
runs out of memory reserved for RX frames, it'll have no other choice
but to drop packets received from the AP. Thus, it is important to
handle RX data interrupts as soon as possible, before handling anything
else.

In addition, since there are enough TX descriptors to go around, it is
better to first send TX frames, and only then handle TX completions.

Fix this by changing the order of function calls in wl1271_irq_work.
