Alex Wang 4a46b24e14 openvswitch: Use exact lookup for flow_get and flow_del. 
Due to the race condition in userspace, there is chance that two
overlapping megaflows could be installed in datapath.  And this
causes userspace unable to delete the less inclusive megaflow flow
even after it timeout, since the flow_del logic will stop at the
first match of masked flow.

This commit fixes the bug by making the kernel flow_del and flow_get
logic check all masks in that case.

Introduced by 03f0d916a (openvswitch: Mega flow implementation).
