cifs: fix creating sockets when using sfu mount options
When running fstest generic/423 with sfu mount option, it
was being skipped due to inability to create sockets:
generic/423 [not run] cifs does not support mknod/mkfifo
which can also be easily reproduced with their af_unix tool:
./src/af_unix /mnt1/socket-two bind: Operation not permitted
Fix sfu mount option to allow creating and reporting sockets.
