iio: imu: st_lsm6dsx: track hw FIFO buffering with fifo_mask

Browse source

Track hw FIFO state introducing fifo_mask since now the accel sensor
can be enabled during suspend/resume in order to trigger the wake-up
enabling the FIFO in st_lsm6dsx_resume even if it was disabled before
the suspend.  Hence we must separately track the fifo state.
