Subject: [iproute PATCH v2 1/3] ss: Remove useless width specifier in process context print

Both local address and service, and remote address and service
fields are already printed out in netlink_show_one() before we
start printing process context, by calling sock_addr_print()
twice.

At this point, sock_addr_print() has already forced the remote
service field to be 'serv_width' wide -- that is, 'serv_width'
width has already been consumed, before we print process
context.

Hence, it makes no sense to force the display width of process
context to be 'serv_width' wide again: previous prints have
filled up the line already. Remove the width specifier and
prefix with a space instead, to keep this consistent with fields
which are displayed after the first output line.
