Brian (privately) reported a "leak" of writeback bitmap in
certain cases, so that backing device can store less pages;
and a theoretical data leak in the trailing bytes of
compressed writeback pages.  Both issues are low risk.

v1 -> v2:
- better commit messages (Andrew)

Sergey Senozhatsky (2):
  zram: do not leak blk idx at the end of writeback
  zram: clear trailing bytes of compressed writeback pages
