x86/efi: Fix off-by-one bug in EFI Boot Services reservation
Current code check boot service region with kernel text region by:
start+size >= __pa_symbol(_text)
The end of the above region should be start + size - 1 instead.
I see this problem in ovmf + Fedora 19 grub boot:
text start:
1000000 md start: 800000 md size: 800000
