datapath-windows: Use spinlock instead of RW lock for ct entry
This patch mainly changes a ndis RW lock for conntrack entry to a
spinlock along with some minor refactor in conntrack. Using
spinlock instead of RW lock as RW locks causes performance hits
when acquired/released multiple times.
- Use NdisInterlockedXX wrapper api's instead of InterlockedXX.
- Update 'ctTotalRelatedEntries' using interlocked functions.
- Move conntrack lock out of NAT module.
Testing:
Verified loading/unloading the driver with driver verified enabled.
Ran TCP/UDP and ICMP traffic.
