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
commit 03776f4516 ("CIFS: Simplify byte range locking code")
'cifs_sb' is not used since commit cb7e9eabb2 ("CIFS: Use
multicredits for SMB 2.1/3 writes").
'tcon' is not used since commit d26e2903fc ("smb3: fix bytes_read statistics")
