lightnvm: disable interleaved metadata
Currently pblk only check the size of I/O metadata and does not take
into account if this metadata is in a separate buffer or interleaved
in a single metadata buffer.
In reality only the first scenario is supported, where second mode will
break pblk functionality during any IO operation.
This patch prevents pblk to be instantiated in case device only
supports interleaved metadata.
