avfilter/avfilter: fix memory leak of filter name in ff_filter_alloc error path

Browse Source 
When ff_filter_alloc fails after the name has been allocated (via
av_strdup), the error handling code frees inputs and input_pads but
misses freeing ret->name, causing a memory leak.

Add av_freep(&ret->name) in the error path before freeing inputs.
