[PATCH] interconnect: icc-clk: check return values of devm_kasprintf()

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

devm_kasprintf() can fail and return NULL, add missing return value
checks.

Fixes: 0ac2a08f42ce ("interconnect: add clk-based icc provider support")
