Subject: iio: accel: adxl372: Fix push to buffers lost samples
Git-commit: 62df81b74393079debf04961c48cb22268fc5fab
Patch-mainline: 5.4-rc3
References: bnc#1151927 5.3.7

One in two sample sets was lost by multiplying fifo_set_size with
sizeof(u16). Also, the double number of available samples were pushed to
the iio buffers.
