[PULL 11/13] mac_oldworld: Drop a variable, use get_system_memory() directly

[Mark Cave-Ayland]

From: BALATON Zoltan <balaton@eik.bme.hu>

Half of the occurances already use get_system_memory() directly
instead of sysmem variable, convert the two other uses to
get_system_memory() too which seems to be more common and drop the
variable.
