Andreas Rheinhardt	3aa0be003e	avcodec/iirfilter: Fix memleak Commit `17e88bf0df` created a memleak by removing a call to ff_iir_filter_free_coeffsp on error; this has been found by Coverity (ID 1464159). This commit fixes the memleak by readding the call to ff_iir_filter_free_coeffsp. Notice that this is not a simple revert, because several macros that were used before `17e88bf0df` were replaced in commit `44863b2c2d` and completely removed in `2658680df4`.
