Subject: alpha: Replace bogus in_interrupt()

in_interrupt() is true for a variety of things including bottom half
disabled regions.  Deducing hard interrupt context from it is dubious at
best.

Use in_irq() which is true if called in hard interrupt context.  Otherwise
calling irq_exit() would do more harm than good.
