drivers: sensors: lis2dh: Fix out-of-bound access

FIX issue #10571 and #10593
atomic_xxx() functions expect the bit argument to be the
position index inside the target integer and not its
numerical representation (e. g. 5 means the 5th bit and not 32).
The original code could potentially override an adiacent variable.
