[PATCH 4.4 029/113] nfs: NFS_SWAP should depend on SWAP

[ 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.

This option enables swapon to work on files located on NFS mounts.
