video: tegra: host: fix sparse warning context imbalance

nvhost_intr.c +87: warning: context imbalance in
	'process_wait_list' - unexpected unlock
nvost_intr.c +87: warning: context imbalance in
	'nvhost_intr_has_pending_jobs' - unexpected unlock
nvhost_intr.c +87: warning: context imbalance in
	'nvhost_intr_add_action' - unexpected unlock

sparse reports context imbalance warnings if there is mismatch in
count of lock/unlock in given context. Here lock is acquired in one
context and released in other context which is expected behaviour.

So annonate function declaration with __acquires and __release to inform
sparse.
