[RISC-V][PR target/119865] Don't free ggc allocated memory
Kaiweng's patch to stop freeing riscv_arch_string was correct, but
incomplete
as there's another path that was freeing that node, which is just plain
wrong
for a node allocated by the GC system.
This patch removes that call to free() which fixes the test. I've spun it
in
my tester and will obviously wait for the pre-commit system to render a
verdict
before moving forward.

* config/riscv/riscv.cc (parse_features_for_version): Do not
explicitly free the architecture string.
