Set vg_mda_copies when pvchange --metadataignore is given.

Browse Source 
When a user explicitly sets a new mda ignore value for a PV, we
should update vg_mda_copies accordingly.  When the VG is written
out, the user would not want the new ignore state to get lost as
a result of the vg_mda_copies value and logic in the vg_write
path.
