ALSA: AACI: fix multiple IRQ claiming
Claiming the IRQ each time a playback or capture interface is opened is wasteful; the second copy of the registered handler is identical to the first and just wastes resources. Track the number of opens and only register the handler when necessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
