commit b6391ac73400eff38377a4a7364bd3df5efb5178 upstream.
Complete read error handling paths for all three kinds of compressed pages:
For cache-managed pages, PG_uptodate will be checked since read_endio will unlock and SetPageUptodate for these pages;
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;
For staging pages, PG_error is used, which is similar to what we do for inplaced pages.

It's my pleasure to backport related conflict bugfixes to stable kernels. :)
Thanks, Gao Xiang
