cifs: Do not attempt to call CIFSGetSrvInodeNumber() without CAP_INFOLEVEL_PASSTHRU 



CIFSGetSrvInodeNumber() uses SMB_QUERY_FILE_INTERNAL_INFO (0x3ee) level
which is SMB PASSTHROUGH level (>= 0x03e8). SMB PASSTHROUGH levels are
supported only when server announce CAP_INFOLEVEL_PASSTHRU.

So add guard in cifs_query_file_info() function which is the only user of
CIFSGetSrvInodeNumber() function and returns -EOPNOTSUPP when server does
not announce CAP_INFOLEVEL_PASSTHRU.
