Only reason for having two different register functions was because of
ipt_MASQUERADE and ip6t_MASQUERADE being two different modules.
Previous patch merged those into xt_MASQUERADE, so we can merge this too.

Both are now implemented by nf_nat_masquerade.c, so no need to keep
different headers.

Otherwise, we get notifier list corruption.
This is the most simple fix: remove the device notifier call chain
from the ipv6 masquerade register function and handle it only
in the ipv4 version.
The better fix is merge
nf_nat_masquerade_ipv4/6_(un)register_notifier
into a single
nf_nat_masquerade_(un)register_notifiers
but to do this its needed to first merge the two masquerade modules
into a single xt_MASQUERADE.
Furthermore, we need to use different refcounts for ipv4/ipv6
until we can merge MASQUERADE.
