erofs: fix memory leak of LZMA global compressed deduplication
[ Upstream commit 75a5221630fe5aa3fedba7a06be618db0f79ba1e ]
When stressing microLZMA EROFS images with the new global compressed
deduplication feature enabled (`-Ededupe`), I found some short-lived
temporary pages weren't properly released, which could slowly cause
unexpected OOMs hours later.
Let's fix it now (LZ4 and DEFLATE don't have this issue.)
