[lvm-devel] [PATCH 06/11] Add _vg_mda_copies_get and _vg_mda_copies_set.

[Dave Wysochanski]

Add the 'get' / 'set' functions for vg_mda_copies property.
Since vg_mda_copies is a field that can be changed (see vgchange, etc),
we add a 'set' function here and change the '0' to a '1' in the columns.h
file.
