[PATCH initramfs-tools] initramfs-tools(8): Fix documentation of nfsroot

[Baptiste Jonglez <baptiste.jonglez@imag.fr>]

NFSOPTS is separated by a "," and not a ":" as documented.

Also make it clear that not all options from nfs(5) may be supported.
For instance, "nfsvers=" is not supported by nfsmount and causes the
initrd to loop forever.
