[PATCH v4 6/6] iio: accel: mma8452: Reuse existing dev pointer in mma8452_probe()

[Esben Haabendal]

In commit 32a5c04d4575 ("iio: accel: mma8452: Use dev_err_probe()") the
struct device * pointer was assigned to local variable dev, so we can just
as well reuse that throughout the function for sligthly more readable code.
