qemu_conf: Drop a pair of needless 'cleanup' labels

There are two 'cleanup' labels - one in
virQEMUDriverConfigHugeTLBFSInit() and the other in
virQEMUDriverConfigSetDefaults() that do nothing more than
return and integer value. No memory freeing or anything important
is done there. Drop them in favour of returning immediately.
