ocfs2: Deletion of some unnecessary checks

From: Markus Elfring <[email protected]>

Further update suggestions were taken into account after two patches were applied from static source code analysis.

Markus Elfring (11):
Delete an unnecessary check before unregister_sysctl_table() Delete unnecessary checks before the function call "iput" Less checks in ocfs2_rename() after error detection
One check less in ocfs2_statfs()
Less error log repetition in ocfs2_begin_truncate_log_recovery() Two checks less in ocfs2_local_alloc_slide_window()
Less function calls in ocfs2_shutdown_local_alloc() after error detection Less checks in ocfs2_load_local_alloc()
One function call less in ocfs2_trylock_journal() after error detection Less function calls in ocfs2_replay_journal() after error detection One function call less in ocfs2_journal_shutdown() from input checks
