------------------------------------------------------
From: Jules Irenge <jbi.octave@xxxxxxxxx>
Subject: ocfs2: add missing annotations for ocfs2_refcount_cache_lock() and ocfs2_refcount_cache_unlock()

Sparse reports warnings at ocfs2_refcount_cache_lock()
	and ocfs2_refcount_cache_unlock()

warning: context imbalance in ocfs2_refcount_cache_lock()
	- wrong count at exit
warning: context imbalance in ocfs2_refcount_cache_unlock()
	- unexpected unlock

The root cause is the missing annotation at ocfs2_refcount_cache_lock()
and at ocfs2_refcount_cache_unlock()

Add the missing __acquires(&rf->rf_lock) annotation to
ocfs2_refcount_cache_lock()

Add the missing __releases(&rf->rf_lock) annotation to
ocfs2_refcount_cache_unlock()
