objtool: Fix Clang enum conversion warning
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.
