Subject: cleanup AOP_WRITEPAGE_ACTIVATE use in f2fs v2

Hi all,

this almost entirely cleans up usage of AOP_WRITEPAGE_ACTIVATE in f2fs.

Changes since v1:
 - pick up the bug fix from Chao as patch 1
 - release the folio batch on early exit
 - remove the dead for_reclaim handling
 - keep the ability of the caller to exit early for the redity case
