mdbx: silently put mm_geo.now into [geo.lower...geo.upper] boundaries.
mdbx: silently put mm_geo.now into [geo.lower...geo.upper] boundaries.

Copy-with-compaction by previous version of libmfbx could produce
DB-file less than meta.geo.lower bound, in case actual filling
is low or no data at all.

This is not a problem as there is no damage or loss of data.
Therefore it is better not to consider such situation as an
error, but silently correct it.
