Log Message:
PR lib/51952: Brad Harder: Apply upstream ada959c9

[From upstream tcpdump]
 In pcap_compile(), first check whether the pcap_t is activated.

 Before we allocate or otherwise set up anything, check whether the
 pcap_t is activated, and set the error message string and return -1 if
 it's not.

 That way, we don't go through the cleanup code in that code path -
 there's nothing to clean up.

 Fixes the issue in GitHub pull request #552.
