xfs: fix CIL sparse lock context warnings
Sparse reports:
fs/xfs/xfs_log_cil.c:1127:1: warning: context imbalance in 'xlog_cil_push_work' - different lock contexts for basic block
fs/xfs/xfs_log_cil.c:1380:1: warning: context imbalance in 'xlog_cil_push_background' - wrong count at exit
fs/xfs/xfs_log_cil.c:1623:9: warning: context imbalance in 'xlog_cil_commit' - unexpected unlock
xlog_cil_push_background() has a locking annotations for an rw_sem.
Sparse does not track lock contexts for rw_sems, so the
annotation generates false warnings. Remove the annotation.
xlog_wait_on_iclog() drops the log->l_ic_loglock. The function has a
sparse annotation, but the prototype in xfs_log_priv.h does not.
Hence the warning from xlog_cil_push_work() which calls
xlog_wait_on_iclog(). Add the missing annotation.
