[PATCH 30/30] sgi-xp: Add missing annotation for ocfs2_inode_cache_lock() and ocfs2_inode_cache_unlock()

[Jules Irenge]

Sparse reports a warning at ocfs2_inode_cache_lock()
and ocfs2_inode_cache_unlock()
warning: context imbalance in ocfs2_inode_cache_lock()
	- wrong count at exit

warning: context imbalance in ocfs2_inode_cache_unlock()
	- unexpected unlock
The root cause is a missing annotation at ocfs2_inode_cache_lock()
and at ocfs2_inode_cache_unlock()

Add the missing __acquires(&oi->ip_lock) annotation
Add the missing __releases(&oi->ip_lock) annotation
