genirq/chip: Add buslock back in to irq_set_handler()
[ Upstream commit 5d7e45dd670e42df4836afeaa9baf9d41ca4b434 ]
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.
