[libvirt PATCH] qemu_migration: Use EnterMonitorAsync in qemuDomainGetMigrationBlockers

[Jiri Denemark <jdenemar@xxxxxxxxxx>]

The code is run with an async job and thus needs to make sure a nested
job is acquired before entering the monitor.

While touching the code in qemuMigrationSrcIsAllowed I also fixed the
grammar which was accidentally broken by v8.5.0-140-g2103807e33.
