[PATCH] cosmetic: remove unused function return value

[Ani Sinha <ani@xxxxxxxxxxx>]

qemuBuildPMPCIRootHotplugCommandLine() returns 0 unconditionally. There is no
failure scenario at present. So clean up the code by removing integer return
from the function and also remove the failure check conditional from the
function call.
Also fix indentation for the above function call while at it.
