[PATCH] migration/multifd: Fix build for qatzip

[Peter Xu <peterx@redhat.com>]

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.

Fixes: 80484f9459 ("migration: Introduce 'qatzip' compression method")
Signed-off-by: Peter Xu <peterx@redhat.com>

Qatzip developers: would you help me to double check whether this is the
right fix?
