[libvirt] [PATCH] Remove double close of qemu monitor

When qemuMonitorSetCapabilities() fails, there is no need to
call qemuMonitorClose(), because the caller will already see
the error code and tear down the entire VM. The extra call to
qemuMonitorClose resulted in a double-free due to it removing
a ref count prematurely.
