If find_reloc_by_table_annotate() failed, it means that there
is no relocation info of switch table address in the section
".rela.discard.tablejump_annotate", then objtool can find the
relocation against the nearest instruction before the jump
instruction with find_reloc_by_dest_range(), which points to
the goto table.
