datapath: Do not clear key in ovs_match_init()
		
When executing packets sent from userspace, the majority of the
flow information is extracted from the packet itself and a small
amount of metadata supplied by userspace is added. However, when
adding this metadata, the extracted flow information is currently
being cleared.

This manifests in a problem when executing actions as elements of key are
used when verifying some actions. For example a dec_ttl action verifies the
proto of the flow. An example of a flow that fails as a result of this
problem is:

        ovs-ofctl add-flow br0 "ip actions=dec_ttl,normal"

This is a regression added by "datapath: Mega flow implementation",
a1c564be1e2ffc31f8da09ab654c8ed987907fe5.
