nfs: correct phrasing of nfs-mount-udp option

`gluster volume set help` shows the following typo for the nfs.mount-udp
option:

Option: nfs.mount-udp
Default Value: (null)
Description: set the option to 'on' to enable mountd on UDP. Needed by
Solaris NFS clients if NLM support isneeded

Also, AIX NFS-clients seem to need this option, hence rephrasing the
description to be more helpful.
