f2fs: fix to calculate dirty data during has_not_enough_free_secs() 



In lfs mode, dirty data needs OPU, we'd better calculate lower_p and
upper_p w/ them during has_not_enough_free_secs(), otherwise we may
encounter out-of-space issue due to we missed to reclaim enough
free section w/ foreground gc.
