[PATCH] NFSv4: Add modalias for "nfs4"

[Josh Boyer <jwboyer@redhat.com>]

When NFSv4 is configured, the support goes into the nfs.ko module.
However, nfs-utils seems to pass "nfs4" as the fileststem type for
NFSv4 mounts.  If the nfs module is not already loaded, the kernel
will eventually do a module request for "nfs4".  Apparently, this
has worked until now as the distributions ship a module config file
that manually aliases "nfs4" to "nfs".

There is really no need to do this, as the kernel can provide a
module alias internally for nfs4.  This adds that.
