rGdd5ed53a2f93: RISC-V: Fix feenableexcept return value

The man page says "The feenableexcept(), fedisableexcept(), and
fegetexcept() functions return a bitmap of the exceptions that were
unmasked prior to the call.", so we should return zero not -1.

This fixes one of the fenv tests. There are more failures that I need to look into.
