Subject: objtool: Fix Clang enum conversion warning

From: Lukas Bulwahn <lukas.bulwahn@gmail.com>

commit e7e83dd3ff1dd2f9e60213f6eedc7e5b08192062 upstream.

Fix the following Clang enum conversion warning:

  arch/x86/decode.c:141:20: error: implicit conversion from enumeration
  type 'enum op_src_type' to different enumeration
  type 'enum op_dest_type' [-Werror,-Wenum-conversion]

    op->dest.type = OP_SRC_REG;
		  ~ ^~~~~~~~~~

It just happened to work before because OP_SRC_REG and OP_DEST_REG have
the same value.
