[ Upstream commit 93d6fda7f926451a0fa1121b9558d75ca47e861e ]
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.
Fixes: 67139e36d970 ("erofs: introduce `z_erofs_parse_in_bvecs'")
