f2fs: clear PageError on the read path
When running fault injection test, I hit somewhat wrong behavior in f2fs_gc ->
gc_data_segment():
0. fault injection generated some PageError'ed pages
1. gc_data_segment
-> f2fs_get_read_data_page(REQ_RAHEAD)
2. move_data_page
-> f2fs_get_lock_data_page()
-> f2f_get_read_data_page()
-> f2fs_submit_page_read()
-> submit_bio(READ)
-> return EIO due to PageError
-> fail to move data
