[PATCH 5/5] staging: lustre: selftest: fix _recycle_buffer context imbalance

[Jeremiah Mahler <jmmahler@gmail.com>]

Fix the sparse warning about a context imbalance in the
srpc_service_recycle_buffer function by telling sparse that it
should expect the lock to be held on entry and held on exit.

  drivers/staging/lustre/lnet/selftest/rpc.c:725:20: warning: context imbalance in 'srpc_service_recycle_buffer' - unexpected unlock
