avcodec/iirfilter: Fix memleak Commit 17e88bf0df21906633a7d36d9f2aeeeb5b6d3267 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 17e88bf0df21906633a7d36d9f2aeeeb5b6d3267 were replaced in commit 44863b2c2d5a31d82aafa71cdbd180d6bfbed5b4 and completely removed in 2658680df4fc606522e5f65899afb9a98b47d287.
