gpu: nvgpu: fix mutex leak on fecs_mutex
In gk20a_gr_reset(), we acquire g->gr.fecs_mutex and call a bunch of APIs
But in case any of these APIs fail, we don't release the mutex and just
return the error leaking the mutex
So the next attempt to acquire g->gr.fecs_mutex results in a deadlock
Fix this by releasing the mutex before returning error
