When QPL compression is enabled on the migration channel and the same
dirty page changes from a normal page to a zero page in the iterative
memory copy, the dirty page will not be updated to a zero page again
on the target side, resulting in incorrect memory data on the source
and target sides.
The root cause is that the target side does not record the normal pages
to the receivedmap.
The solution is to add ramblock_recv_bitmap_set_offset in target side
to record the normal pages.

The qatzip series was based on an older commit, it applied cleanly even
though it has conflicts. Neither CI nor myself found the build will break
as it's skipped by default when qatzip library was missing.
Fix the build issues. No need to copy stable as it just landed 9.2.
