[libvirt] [PATCH 45/68] qemu: Replace qemuMigrationAnyCompressionDump

Since every parameter or capability set in qemuMigrationCompression structure is now reflected in qemuMigrationParams structure, we can replace qemuMigrationAnyCompressionDump with a new API which will work on qemuMigrationParams.
