netmap: Release lock to avoid deadlock

[jlucovsky]

Issue: 6755

When NetmapOpen encounters an error opening the netmap device, it'll retry a bit. When the retry limit is reached, it'll shutdown Suricata.

This commit ensures that the device list lock is not held when before closing all open devices before terminating Suricata.
