wl1271: Fix TX starvation
While wl1271_irq_work handles RX directly (by calling wl1271_rx), a different
work is scheduled for transmitting packets. The IRQ work might handle more than
one interrupt during a single call, including multiple TX completion
interrupts. This might starve TX, since no packets are transmitted until all
interrupts are handled.
Fix this by calling the TX work function directly, instead of deferring
it.
