[PATCH] nfsd: Add quotes to client info 'callback address'

[Mark Grimes <mark.grimes@ixsystems.com>]

The 'callback address' in client_info_show is output without quotes
causing yaml parsers to fail on processing IPv6 addresses.
Adding quotes to 'callback address' also matches that used by
the 'address' field.
