riscv: fp: add missing __user pointer annotations
The __user annotations were removed from the {save,restore}_fp_state() function signatures by commit 007f5c358957 ("Refactor FPU code in signal setup/return procedures"), but should be present, and sparse warns when they are not applied. Add them back in. This change should have no functional impact.
