[PATCH v6 03/15] ubifs: Fix wrong number of inodes locked by ui_mutex in ubifs_inode comment

[Zhihao Cheng]

Since 9ec64962afb1702f75b("ubifs: Implement RENAME_EXCHANGE") and
9e0a1fff8db56eaaebb("ubifs: Implement RENAME_WHITEOUT") are applied,
ubifs_rename locks and changes 4 ubifs inodes, correct the comment
for ui_mutex in ubifs_inode.
