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.
