RISC-V: Remove a loop in the ISA parser
Since commit e601909a3287bf541c6a7d82214bb387d2c76d82 ("RISC-V: Support to parse the multi-letter prefix in the architecture string.") changed so that all prefixed extensions are parsed in single riscv_parse_prefixed_ext call, a "while" loop on riscv_parse_subset is no longer required. bfd/ChangeLog: * elfxx-riscv.c (riscv_parse_subset): Remove unnecessary loop.
