[PATCH] RISC-V: Fix xlen to flen typo in FP reg handling.

[Jim Wilson <jimw@sifive.com>]

This fixes a bug in FP register handling for targets where xlen != flen.
Tested against riscv-test/debug where it fixes a few failures.  Also tested
on RV64GC linux with the gdb testsuite where it has no effect.

	gdb/
	* riscv-tdep.c (riscv_register_type): Use riscv_isa_flen for FP regs
	not riscv_isa_xlen.
