[PATCH 3/3] iio: accel: kxsd9: use dev_err_probe()

[Biren Pandya <birenpandya@gmail.com>]

Modernize the error paths in kxsd9_common_probe() by using
dev_err_probe() instead of dev_err() when handling failures from
regulators and buffer setup.

This simplifies the error handling and properly suppresses annoying
and unnecessary log spam during -EPROBE_DEFER cases when regulators
are not yet available during boot.
