erofs: fix memory leak on short-lived bounced pages

Browse source

Both MicroLZMA and DEFLATE algorithms can use short-lived pages on
demand for the overlapped inplace I/O decompression.

However, those short-lived pages are actually added to
`be->compressed_pages`.  Thus, it should be checked instead of
`pcl->compressed_bvecs`.

The LZ4 algorithm doesn't work like this, so it won't be impacted.
