cifs: enable fscache iff fsc mount option is used explicitly
Currently, if CONFIG_CIFS_FSCACHE is set, fscache is enabled on files opened as read-only irrespective of the 'fsc' mount option. Fix this by enabling fscache only if 'fsc' mount option is specified explicitly. Remove an extraneous cFYI debug message and fix a typo while at it.
