Ville Syrjälä ba24d63dd3 ath9k: Avoid a potential deadlock 
Lockdep warns us that sc_pm_lock and cc_lock can cause a deadlock when
cc_lock is acquired by itself with interrupts enabled. Disable irqs
whenever taking cc_lock to avoid this.

[   19.094524] kworker/u2:0/5 just changed the state of lock:
[   19.094578]  (&(&sc->sc_pm_lock)->rlock){-.-...}, at: [<f836c00e>] ath_isr+0x15e/0x200 [ath9k]
[   19.094674] but this lock took another, HARDIRQ-unsafe lock in the past:
[   19.094731]  (&(&common->cc_lock)->rlock){+.-...}
[   19.094741]

               and interrupts could create inverse lock ordering between them.

               other info that might help us debug this:
