x86/kprobes: Fix typo transferred from Intel manual
The arch/x86/lib/x86-opcode-map.txt file [used by the
kprobes instruction decoder] contains the line:
af: SCAS/W/D/Q rAX,Xv
This is what the Intel manuals show, but it's not correct.
The 'X' stands for:
Memory addressed by the DS:rSI register pair (for example, MOVS, CMPS, OUTS, or LODS).
On the other hand 'Y' means (also see the ae byte entry for
SCASB):
Memory addressed by the ES:rDI register pair (for example, MOVS, CMPS, INS, STOS, or SCAS).
