[PATCH v1 06/14] domain_conf: add virDomainMergeBlkioDevice()

Mon Feb 10 22:05:12 UTC 2020
lxcDomainMergeBlkioDevice() and -qemuDomainMergeBlkioDevice()
are the same functions. Put the code in a new
virDomainMergeBlkioDevice() inside domain_conf.c and update
both callers.
This change is a preliminary step for more code reduction of
cgroup related code inside lxcDomainSetBlkioParameters() and
qemuDomainSetBlkioParameters().
