Leon Romanovsky 3c611d40c6 xfrm: speed-up lookup of HW policies
Devices that implement IPsec packet offload mode should offload SA and
policies too. In RX path, it causes to the situation that HW will always
have higher priority over any SW policies.

It means that we don't need to perform any search of inexact policies
and/or priority checks if HW policy was discovered. In such situation,
the HW will catch the packets anyway and HW can still implement inexact
lookups.

In case specific policy is not found, we will continue with packet lookup and
check for existence of HW policies in inexact list.

HW policies are added to the head of SPD to ensure fast lookup, as XFRM
iterates over all policies in the loop.

The same solution of adding HW SAs at the begging of the list is applied
to SA database too. However, we don't need to change lookups as they are
sorted by insertion order and not priority.
