[ Upstream commit 001470fed5959d01faecbd57fcf2f60294da0de1 ]
Since the size value is added to the base address to yield the last valid
byte address of the GDT, the current size value of startup_gdt_descr is
incorrect (too large by one), fix it.
[ mingo: This probably never mattered, because startup_gdt[] is only used
in a very controlled fashion - but make it consistent nevertheless. ]
Fixes: 866b556efa12 ("x86/head/64: Install startup GDT")
