ath9k: correct ath9k_hw_set_interrupts

Browse Source 
Commit 4df3071ebd "ath9k_hw: optimize
interrupt mask changes", changed ath9k_hw_set_interrupts function to
enable interrupts regardless of function argument, what could possibly
be wrong. Correct that behaviour and check "ints" arguments before
enabling interrupts, also disable interrupts if ints do not have
ATH9K_INT_GLOBAL flag set.
