PR28172, bfin_pcrel24_reloc heap-buffer-overflow

bfin pcrel24 relocs are weird, they apply to the reloc address minus
two.  That means reloc addresses of 0 and 1 are invalid.  Check that,
and fix other reloc range checking.

PR 28172
* elf32-bfin.c (bfin_pcrel24_reloc): Correct reloc range check.
(bfin_imm16_reloc, bfin_byte4_reloc, bfin_bfd_reloc): Likewise.
(bfin_final_link_relocate): Likewise.
