dm-cache: fix warnings about duplicate slab caches
The commit 4c39529663b9 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-cache
code.
The dm-cache code allocates a slab cache for each device. This commit
changes it to allocate just one slab cache in the module init function.
