avcodec/frame_thread_encoder: Fix segfault on allocation error

Fixes a segfault from av_fifo_size(NULL) that happens in
ff_frame_thread_encoder_free if the fifo couldn't be allocted;
furthermore the mutexes and conditions that are destroyed in
ff_frame_thread_encoder_free are not even initialized at this point,
so don't call said function.
