[PATCH] cifs: Fix uninitialized variable in set_chmod_dacl()

[Dan Carpenter <dan.carpenter@oracle.com>]

Initialize the "nmode" variable earlier to prevent an uninitialized
variable bug when we do "size += setup_special_mode_ACE(pntace, nmode);"

Fixes: 253374f7557e ("cifs: Fix unix perm bits to cifsacl conversion for "other" bits.")
