[PATCH 17/17] bfs: replace get_zeroed_page() with kzalloc()

[Mike Rapoport (Microsoft)]

bfs_dump_imap() allocates temporary buffer with get_zeroed_page().

kmalloc() is a better API for such use and it also provides better
scalability and more debugging possibilities.

Replace use of get_zeroed_page() with kzalloc().
