[PATCH 19/23] arch: c6x: use generic irq error counter

["Enrico Weigelt, metux IT consult" <info@xxxxxxxxx>]

Use the newly introduced irq error counter, that's already maintained
by all callers of ack_bad_irq(), in order to remove duplicate code.

Signed-off-by: Enrico Weigelt, metux IT consult <info@xxxxxxxxx>
