Intel DSA offloading is an optional feature that turns on if
proper hardware and software stack is available. To turn on
DSA offloading in multifd live migration:
multifd-dsa-accel="[dsa_dev_path1] ] [dsa_dev_path2] ... [dsa_dev_pathX]"
This feature is turned off by default.

This patch breaks make check:
43/357 qemu:qtest+qtest-x86_64 / qtest-x86_64/test-hmp ERROR 0.52s
79/357 qemu:qtest+qtest-x86_64 / qtest-x86_64/migration-test ERROR 3.59s
167/357 qemu:qtest+qtest-x86_64 / qtest-x86_64/qmp-cmd-test ERROR 3.68s
Make sure you run make check before posting. Ideally also run the series
through the Gitlab CI on your personal fork.

Reverted those now.
