cifs: don't use CIFSGetSrvInodeNumber in is_path_accessible
Because it's lighter weight, CIFS tries to use CIFSGetSrvInodeNumber to verify the accessibility of the root inode and then falls back to doing a full QPathInfo if that fails with -EOPNOTSUPP. I have at least a report of a server that returns NT_STATUS_INTERNAL_ERROR rather than something that translates to EOPNOTSUPP. Rather than trying to be clever with that call, just have is_path_accessible do a normal QPathInfo. That call is widely supported and it shouldn't increase the overhead significantly.
