[CIFS] Change semaphore to mutex for cifs lock_sem
Originally at http://lkml.org/lkml/2006/9/2/86 The recent change to "allow Windows blocking locks to be cancelled via a CANCEL_LOCK call" introduced a new semaphore in struct cifsFileInfo, lock_sem. However, semaphores used as mutexes are deprecated these days, and there's no reason to add a new one to the kernel. Therefore, convert lock_sem to a struct mutex (and also fix one indentation glitch on one of the lines changed anyway).
