cpufreq: scpi: fix static checker warning cdev isn't an ERR_PTR

Commit 343a8d17fa8d (cpufreq: scpi: remove arm_big_little dependency)
leads to the following static checker warning:

	drivers/cpufreq/scpi-cpufreq.c:203 scpi_cpufreq_ready()
	warn: 'cdev' isn't an ERR_PTR

of_cpufreq_cooling_register() returns NULL on error. This patch removes
the incorrect IS_ERR check on the returned pointer.
