[PATCHES] Fixes for daq_nfq

Attached is a patch that fixes a couple of issues (I think they are issues,
anyways...) we have found in the NFQ DAQ module in Snort 2.9.0.
nfq_get_timestamp (for us) often returns -1, trying to tell us that it does
not have a timestamp for this packet, and the first part of this patch just
uses the current time when writing the packet header. Many parts of snort
seem to depend on having a valid timestamp in the packet header, so this would
definitely break it.
The second part of the patch removes the return statement from the packet
handling loop inside the NFQ DAQ -- under certain conditions,
nfq_handle_packet will break and return early (before calling the callback);
this causes snort to either freeze or exit, both undesirable outcomes,
especially when Snort is being used in inline mode.
If any of these changes are terribly shortsighted or just plain wrong, please
let me know. I haven't delved that deep into the Snort code yet.
