[PATCH v8 3/5] mac_oldworld: Drop a variable, use get_system_memory() directly

[BALATON Zoltan via <qemu-devel@nongnu.org>]

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.
