[libvirt] [PATCH 1/6] Add missing checks for QEMU domain state in memory parameter code

[Daniel P. Berrange]

qemuDomainSetMemoryParameters and qemuDomainGetMemoryParameters
forgot to do a check on virDomainIsActive(), resulting in bogus
error messages from later parts of their impl

* src/qemu/qemu_driver.c: Add missing checks on virDomainIsActive()
