Special handling for MP table in low memory is only necessary if there are
tables in low memory.
This removes a hang when HAVE_LOW_TABLES=0 and HAVE_HIGH_TABLES=1. With this
patch I can boot all the way to a payload. Tested on a Supermicro H8DME.
Many thanks to Patrick Georgi for figuring this out.
