Re: [PATCH 1/3] staging: erofs: fix error handling when failed to read compresssed data

Complete read error handling paths for all three kinds of compressed pages:

1. For cache-managed pages, PG_uptodate will be checked since read_endio will unlock and SetPageUptodate for these pages;

2. For inplaced pages, read_endio cannot SetPageUptodate directly since it should be used to mark the final decompressed data, PG_error will be set with page locked for IO error instead;

3. For staging pages, PG_error is used, which is similar to what we do for inplaced pages.
