[PATCH v2] iio: accel: bmc150: check reset write error

[Carlos Casadiego via B4 Relay <devnull+cdcp206.gmail.com@kernel.org>]

From: Carlos Casadiego <cdcp206@gmail.com>

The software reset is required to bring the device into a known
state before reading the chip ID.

Check the return value of regmap_write() and abort initialization if
the reset command cannot be written.
