[PATCH] regulator: cros-ec-regulator: Fix double free of desc->name.

[Pi-Hsun Shih <pihsun@chromium.org>]

The desc->name field is allocated with devm_kstrdup, but is also kfreed
on the error path, causing it to be double freed. Remove the kfree on
the error path.

Fixes: 8d9f8d57e023 ("regulator: Add driver for cros-ec-regulator")
