zram: remove UNDER_WB and simplify writeback
We now have only one active post-processing at any time, so we don't have
same race conditions that we had before. If slot selected for
post-processing gets freed or freed and reallocated it loses its PP_SLOT
flag and there is no way for such a slot to gain PP_SLOT flag again until
current post-processing terminates.
