erofs: fix setting up pcluster for temporary pages
pcluster should be only set up for all managed pages instead of
temporary pages. Since it currently uses page->mapping to identify,
the impact is minor for now.
[ Update: Vladimir reported the kernel log becomes polluted
because PAGE_FLAGS_CHECK_AT_FREE flag(s) set if the page
allocation debug option is enabled. ]
