[libvirt] [PATCH v2 35/73] qemu: Use qemuMigrationParamsFromFlags everywhere

Wednesday, 11 April 2018

Every migration entry point in qemu_driver is supposed to call
qemuMigrationParamsFromFlags to transform flags and parameters into
qemuMigrationParams structure and pass the result to qemuMigration*
APIs.
