If we set vgmetadatacopies value which less than PV available numbers in a VG,
and use pvmetadataignore default 0, vgcreate save metadata to all pvs, included those
set MDA_IGNORED flags PV. It is misleading into thinking that the set MDA_IGNORED PV
is still in use. It also influence vgcreate performance in lots of PV environment.
So, we add filter condition to avoid write metadata to those set MDA_IGNORED flags PV.
