Francesco Lavra a8e88edfd6 iio: accel: adxl380: Avoid reading more entries than present in FIFO 
[ Upstream commit c1b1401522 ]

The interrupt handler reads FIFO entries in batches of N samples, where N
is the number of scan elements that have been enabled. However, the sensor
fills the FIFO one sample at a time, even when more than one channel is
enabled. Therefore,the number of entries reported by the FIFO status
registers may not be a multiple of N; if this number is not a multiple, the
number of entries read from the FIFO may exceed the number of entries
actually present.

To fix the above issue, round down the number of FIFO entries read from the
status registers so that it is always a multiple of N.
