qemu_process: Accept VIR_QEMU_PROCESS_START_RESET_NVRAM flag when starting a domain
qemu_process: Accept VIR_QEMU_PROCESS_START_RESET_NVRAM flag when starting a domain

In one of my previous commits I've fixed the value of
VIR_QEMU_PROCESS_START_RESET_NVRAM flag (which was masking
another value). But what I forgot to do is update virCheckFlags()
calls in two places where the flag is passed: qemuProcessLaunch()
and qemuProcessStart().
