[PATCH] qemuProcessSetupDisksTransientHotplug: Add checking set-action capability

From: Masayoshi Mizuma <m.mizuma(a)jp.fujitsu.com&gt; The VM is terminated abnormally when <transient shareBacking='yes'/> is set to the disk option and the qemu doesn't have set-action capability. # virsh start guest01 error: Failed to start domain 'guest01' error: internal error: qemu unexpectedly closed the monitor # Add checking the capability before system_reset QMP command is sent so that the VM can stop correctly when the qemu doesn't have the cap.
