Felix Fietkau e0e9bc82fb ath9k_hw: optimize tx status descriptor processing 
Disassembly shows, that at least on MIPS, the compiler generates a lot of
memory accesses to the same location in the descriptor field parsing.
Since it is operating on uncached memory, this can be quite expensive in
this hot path.
Change the code a bit to help the compiler optimize it properly, and get
rid of some unused fields in the ath_tx_status struct.

Felix Fietkau 45684c75f9 ath9k_hw: small optimization in ar9002_hw_get_isr 
ah->config.rx_intr_mitigation does not need to be checked before checking
the rx interrupt mask for AR_ISR_RXMINTR or AR_ISR_RXINTM, as those
interrupts will be masked out if rx interrupt mitigation is disabled.

Avoid reading AR_ISR_S5_S twice by reordering the code to be more concise.
