Many bdev modules create their own bdev structure
with spdk_bdev as the first member. bdev.c currently
uses the spdk_bdev pointer as its io_device handle,
forcing bdev modules to pick something different.
Change this to use the spdk_bdev pointer + 1 bytes
as its io_device handle. The actual handle does not
really matter - it just needs to be unique. This will
simplify bdev module development.
