[PATCH REPOST] alpha: Replace bogus in_interrupt()

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

From: Thomas Gleixner <tglx@linutronix.de>

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.
