[PREVIEW] [PATCH 2/4] staging: erofs: cached compressed pages could be relocked

[Gao Xiang]

Cached compressed pages will all unlock when IO ends by design.
So compressed pages will be up-to-date and unlocked when
decompressing typically.

However there is an exception, since compressed pages are
unlocked, it could be locked by the reclaim path. Therefore,
the redundant BUG_ON in z_erofs_vle_unzip should be dropped.
