[PATCH 01/10] zram: prefix backends printk-s

[Sergey Senozhatsky]

Currently, zram backends prefix printk-s with their names,
which may look a little confusing, e.g.

	[   30.859567] zstd: alloc size 408128

In addition, prefix backend names with "zram:" so it's
clear that the message is coming from a zram backend.
