fs/cifs: fix uninitialised variable warnings
In some error conditions, resp_buftype can be passed uninitialised to free_rsp_buf(), potentially resulting in a spurious debug message. If resp_buftype randomly had the value 1 (CIFS_SMALL_BUFFER) then this would log a debug message. The rsp pointer is initialised to NULL so there is no other side-effect.
