[PATCH] [fuse] Add lock annotations to request_end andfuse_read_interrupt

[Josh Triplett]

request_end and fuse_read_interrupt release fc->lock.  Add lock annotations to
these two functions so that sparse can check callers for lock pairing, and so
that sparse will not complain about these functions since they intentionally
use locks in this manner.
