[PATCH 5.15 722/913] f2fs: compress: fix to print raw data size in error path of lz4 decompression

[Greg Kroah-Hartman]

From: Chao Yu <chao@xxxxxxxxxx>

[ Upstream commit d284af43f703760e261b1601378a0c13a19d5f1f ]

In lz4_decompress_pages(), if size of decompressed data is not equal to
expected one, we should print the size rather than size of target buffer
for decompressed data, fix it.
