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

Browse source

CIFSSMBRenameOpenFile() uses SMB_SET_FILE_RENAME_INFORMATION (0x3f2) level
which is SMB PASSTHROUGH level (>= 0x03e8). SMB PASSTHROUGH levels are
supported only when server announce CAP_INFOLEVEL_PASSTHRU.

All usage of CIFSSMBRenameOpenFile() execept the one is already guarded by
checks which prevents calling it against servers without support for
CAP_INFOLEVEL_PASSTHRU.

The remaning usage without guard is in cifs_do_rename() function, so add
missing guard here.
