PR binutils/22875: FRV/ELF: Prevent an out-of-bounds howto table access

Prevent an out-of-bounds `elf32_frv_howto_table' table access in
`frv_info_to_howto_rela' by using the size of the table rather than
R_FRV_max to determine the number of entries in the contiguous regular
FRV relocation range defined and described in the table.

	* elf32-frv.c (frv_info_to_howto_rela): Correct the range check
	for `elf32_frv_howto_table' table access.
