cifs: remove set but not used variables
Fixes gcc '-Wunused-but-set-variable' warning: fs/cifs/file.c: In function cifs_lock: fs/cifs/file.c:1696:24: warning: variable cinode set but not used [-Wunused-but-set-variable] fs/cifs/file.c: In function cifs_write: fs/cifs/file.c:1765:23: warning: variable cifs_sb set but not used [-Wunused-but-set-variable] fs/cifs/file.c: In function collect_uncached_read_data: fs/cifs/file.c:3578:20: warning: variable tcon set but not used [-Wunused-but-set-variable] 'cinode' is never used since introduced by commit03776f4516
("CIFS: Simplify byte range locking code") 'cifs_sb' is not used since commitcb7e9eabb2
("CIFS: Use multicredits for SMB 2.1/3 writes"). 'tcon' is not used since commitd26e2903fc
("smb3: fix bytes_read statistics") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: YueHaibing <yuehaibing@huawei.com> Signed-off-by: Steve French <stfrench@microsoft.com>
