Avoid triggering lockdep checker in ath_hw_reset()

Use spin_lock_irqsave_nested() instead of spin_lock_irqsave().  Use a
separate counter for the locking subclass, so that we don't exceed the
maximal value of 8.  We have 10 queues, but inactive queues don't get a
locking subclass number.

Provide a replacement for spin_lock_irqsave_nested() for kernels older
than 2.6.19.
