iio: accel: bma400: Fix smatch warning based on use of unintialized value.

Browse source

Only specific bits in this value are ever used and those are initialized,
but that is complex to reason about in a checker. Hence, initialize
the value to zero and avoid the complexity.

Smatch warning:
drivers/iio/accel/bma400_core.c:1287 bma400_tap_event_en()
error: uninitialized symbol 'field_value'.
