Zhang Xiaoxu e98ecc6e94 cifs: Fix the error length of VALIDATE_NEGOTIATE_INFO message 
Commit d5c7076b77 ("smb3: add smb3.1.1 to default dialect list")
extend the dialects from 3 to 4, but forget to decrease the extended
length when specific the dialect, then the message length is larger
than expected.

This maybe leak some info through network because not initialize the
message body.

After apply this patch, the VALIDATE_NEGOTIATE_INFO message length is
reduced from 28 bytes to 26 bytes.

Fixes: d5c7076b77 ("smb3: add smb3.1.1 to default dialect list")
