Subject: objtool: Fix IRET's opcode

From: Jiri Slaby <[email protected]>

[ Upstream commit b5b46c4740aed1538544f0fa849c5b76c7823469 ]

The IRET opcode is 0xcf according to the Intel manual and also to objdump of my vmlinux:

1ea8: 48 cf iretq

Fix the opcode in arch_decode_instruction().

The previous value (0xc5) seems to correspond to LDS.
