[PATCH 6.18 186/277] iio: imu: adis16550: fix swapped gyro/accel filter functions

From: Antoniu Miclaus <antoniu.miclaus@analog.com>

commit ea7e2e43d768102e2601dbbda42041c78d7a99f9 upstream.

The low-pass filter handlers for IIO_ANGL_VEL and IIO_ACCEL call each
other's filter functions in both read_raw and write_raw. Swap them so
each channel type uses its correct filter accessor.
