[PATCH] RISC-V: Default-initialize variable.

[Robin Dapp]

Hi,

this patch initializes saved_vxrm_mode to VXRM_MODE_NONE.  This is a
warning (but no error) when building the compiler so better fix it.

Regtested on rv64gcv_zvl512b.  Going to commit as obvious if the CI
is happy.

Regards
Robin

        * config/riscv/riscv.cc (singleton_vxrm_need): Init
        saved_vxrm_mode.
