Atish Patra 7ce916f4e9 drivers/perf: riscv: Return error for default case ...

[ Upstream commit 2c206cdede ]

If the upper two bits has an invalid valid (0x1), the event mapping
is not reliable as it returns an uninitialized variable.

Return appropriate value for the default case.

Fixes: f0c9363db2 ("perf/riscv-sbi: Add platform specific firmware event handling")
