Leonard Crestez b110cf2b74 PM / devfreq: Check NULL governor in available_governors_show 
commit d68adc8f85 upstream.

The governor is initialized after sysfs attributes become visible so in
theory the governor field can be NULL here.

Fixes: bcf23c79c4 ("PM / devfreq: Fix available_governor sysfs")
