f2fs: deallocate compressed pages when error happens
[ Upstream commit 827f02842e40ea2e00f401e8f4cb1bccf3b8cd86 ]
In f2fs_write_multi_pages(), f2fs_compress_pages() allocates pages for
compression work in cc->cpages[]. Then, f2fs_write_compressed_pages() initiates
bio submission. But, if there's any error before submitting the IOs like early
f2fs_cp_error(), previously it didn't free cpages by f2fs_compress_free_page().
Let's fix memory leak by putting that just before deallocating cc->cpages.
Fixes: 4c8ff7095bef ("f2fs: support data compression")
