Mikulas Patocka 42964e4b5e dm-bufio: fix warnings about duplicate slab caches ...

The commit 4c39529663 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-bufio
code. The dm-bufio code allocates a slab cache with each client. It is
not possible to preallocate the caches in the module init function
because the size of auxiliary per-buffer data is not known at this point.

So, this commit changes dm-bufio so that it appends a unique atomic value
to the cache name, to avoid the warnings.
