mld6: Ensure that mld_domifattach() always succeeds
mld_domifattach() does a memory allocation under the global MLD mutex
and so can fail, but no error handling prevents a null pointer
dereference in this case. The mutex is only needed when updating the
global softc list; the allocation and static initialization of the softc
does not require this mutex. So, reduce the scope of the mutex and use
M_WAITOK for the allocation.
