[CIFS] Prevent OOPs when mounting with remote prefixpath.
Fixes OOPs with message 'kernel BUG at fs/cifs/cifs_dfs_ref.c:274!'.
Checks if the prefixpath in an accesible while we are still in cifs_mount
and fails with reporting a error if we can't access the prefixpath
Should fix Samba bugs 6086 and 5861 and kernel bug 12192
