hv.c: silence compiler warning

hv.c: In function ‘Perl_hv_undef_flags’:
hv.c:2053:35: warning: ‘orig_ix’ may be used uninitialized in this function [-Wmaybe-uninitialized]
             PL_tmps_stack[orig_ix] = &PL_sv_undef;

The warning is bogus, as we only use orig_ix if "save" is true,
and if "save" is true we will have initialized orig_ix. However
initializing it in the first place avoids any issue
