Subject: [PREVIEW] [PATCH chao/erofs-dev 3/3] staging: erofs: managed pages
 could be locked at the time of decompression

Managed compressed pages should be unlocked when IO ends by design.
Therefore, these pages will be up-to-date and unlocked at the time
of decompression in general.

However managed pages could be re-locked in some other paths, such as
the reclaim path. Let's remove the related assertion in decompression.
