Don't zero non-real arrays
A minor difference in behaviour introduced by the rewrite of av_extend_guts
in 440c1856 and 399fef93 is that when the SV* array is first acquired, we
now zero its contents regardless of whether that is needed - and add an
extra label and 'goto' to do so.
This commit restores the original behavious: for non-refcounted arrays such
as @_ and pad arrays this is not needed, and for pads in particular we may
hit this path many times during the course of a program.
