RISC-V: Remove a loop in the ISA parser

Browse Source 
Since commit e601909a32 ("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.
