swapfile: disable swapon for bs > ps devices

Devices which have a requirement for bs > ps cannot be supported for
swap as swap still needs work. Now that the block device cache sets the
min order for block devices we need this stop gap otherwise all
swap operations are rejected.

Without this you'll end up with errors on these devices as the swap
code still needs much love to support min order.

With this we at least now put a stop gap of its use, until the
swap subsystem completes its major overhaul:

mkswap: /dev/nvme3n1: warning: wiping old swap signature.
