Yuan Liu a523bc5216 multifd: bugfix for incorrect migration data with qatzip compression 
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.
