ss: fix NULL dereference when rendering without header
When ss is invoked with the no-header flag, if the query doesn't return
any result, render() is called with 'buffer' uninitialized. This
currently leads to a segfault. Ensure that buffer is initialized before
rendering.
The bug can be triggered with: ss -H sport = 100000

Title:
iproute2 segfaults when filtering sockets
Status in iproute2 package in Ubuntu:
Fix Released
Status in iproute2 source package in Bionic:
Confirmed
Bug description:
When in Ubuntu Bionic, if one calls:
$ sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst 127.0.0.1
tcp 0 0
127.0.0.1:58910 127.0.0.1:22
users:(("ssh",pid=11672,fd=3)) timer:(keepalive,119min,0)
it works. Just like when in Groovy:
$ sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst 127.0.0.1
tcp 0 0
127.0.0.1:58908 127.0.0.1:22
users:(("ssh",pid=1488591,fd=3)) timer:(keepalive,119min,0)
but.. if there is nothing to show, in Bionic we get a segfault:
$ sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst 127.0.0.1
Segmentation fault
