because av_bsf_list_parse_str called av_bsf_get_null_filter,
av_bsf_get_null_filter called av_bsf_alloc, and av_bsf_alloc
should set a value to the *pctx before return success or failed,

av_bsf_free will free invalid pointer when av_bsf_alloc failed.
because av_bsf_list_parse_str called av_bsf_get_null_filter,
av_bsf_get_null_filter called av_bsf_alloc, and av_bsf_alloc
should set a value to the *pctx before return success or failed,
because it dose not initial a null pointer ever,
