iSeries: Fix up viotty_ioctl BKL locking fallout

The bogus code to call into the n_tty layer got removed in commit
8bc5fb6abb670fa9079cd1994f016a39f99698fe ("Remove bogons from the
iSeries console"), but it left a now uninitialized "return ret;" around.

Not that this code has ever even compiled since the BKL pushdown, since
not only is "ret" no longer initialized, it was never actually declared
even originally.

Replace it with a "return -ENOIOCTLCMD"
