[ Upstream commit 474c4f306eefbb21b67ebd1de802d005c7d7ecdc ]
If CONFIG_SWAP=n, it does not make much sense to offer the user the
option to enable support for swapping over NFS, as that will still fail
at run time:
# swapon /swap
swapon: /swap: swapon failed: Function not implemented
Fix this by adding a dependency on CONFIG_SWAP.
Fixes: a564b8f0398636ba ("nfs: enable swap on NFS")
