[PATCH] bio: don't write "bio: create slab" messages to syslog

[Mikulas Patocka]

When using device mapper, there are many "bio: create slab" messages in
the log. Device mapper targets have different front_pad, so each time when
we load a target that wasn't loaded before, we allocate a slab with the
appropriate front_pad and there is associated "bio: create slab" message.

This patch removes these messages, there is no need for them.

Agreed, it's time to kill off that message. Applied, thanks.
