genirq/manage: Add buslock back in to enable_irq()

Browse Source 
[ Upstream commit ef3330b99c01bda53f2a189b58bed8f6b7397f28 ]

The locking was changed from a buslock to a plain lock, but the patch
description states there was no functional change. Assuming this was
accidental so reverting to using the buslock.
