RISC-V: Fix hartid mask handling for hartid 31 and up
Jessica reports that using "1 << hartid" causes undefined behavior for
hartid 31 and up.
Fix this by using the BIT() helper instead of an explicit shift.
Reported-by: Jessica Clarke <[email protected]>
Fixes: 26fb751ca37846c9 ("RISC-V: Do not use cpumask data structure for hartid bitmap")
