Subject: [PATCH v2 1/2] cpufreq: ti-cpufreq: Fix an incorrect error return value

Commit 05829d9431df ("cpufreq: ti-cpufreq: kfree opp_data when
failure") has fixed a memory leak in the failure path, however
the patch returned a positive value on get_cpu_device() failure
instead of the previous negative value. Fix this incorrect error
return value properly.
