usNIC calls BUG_ON(spin_is_locked..) at few places. In some of these instances, the call is made while holding a spinlock. Change all BUG_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.
