Rebased + rename path to paths in one more function.
Ján Tomko (7):
qemuDomainNamespaceTeardownHostdev: rename path to paths
qemuDomainNamespaceSetupHostdev: rename path to paths
Introduce qemuDomainNamespaceMknodPaths
Introduce qemuDomainNamespaceMknodPath
Introduce qemuDomainNamespaceUnlinkPaths
Introduce qemuDomainNamespaceUnlinkPath
Do not pass driver to qemuDomainNamespace{Setup,Teardown} functions
