Verma, Vishal L Nov. 4, 2019, 8:16 p.m. UTC
Replace the open coded namespace active check with the one provided by
libndctl - ndctl_namespace_is_active().

is_namespace_active() additionally checked for a non-NULL 'ndns', which
the libndctl API doesn't do. However, all the callers either performed
that check themselves, or made prior assumptions about ndns being valid
by dereferencing it earlier.
