Mirror my changes of src/sbin/gpt/create.c 1.4 in migrate.c;

Use less bogus CHS addresses in PMBR.
With the ending head set at 0xff one machine I have will never leave
the initial startup screen if such a disk is present. Additionally,
Wikipedia suggests without citiation that 254 is the maximium allowable
value for the head, and this seems to be the case.
