Push all of the usnic device forwarding state - such as mtu, mac - to
usnic_fwd_dev. Furthermore, usnic_fwd.h exposes a improved interface
for rest of the usnic code. The primary improvement is that
usnic_fwd.h's flow management interface takes in high-level *filter*
and *action* structures now, instead of low-level paramaters such as
vnic_idx, rq_idx.

usNIC calls WARN_ON(spin_is_locked..) at few places. In some of these
instances, the call is made while holding a spinlock. Change
all WARN_ON(spin_is_locked...) calls in usNIC to
lockdep_assert_held to make it fool-proof bc the latter can be
called while holding a spinlock and unlike spin_is_locked,
lockdep_assert_held also works correctly on UP.
