The data protected by the inbound (oob -> in-band traffic) buffer lock
is frequently accessed from the in-band stage by design, where hard
irqs should be disabled. Conversely, the out-of-band sections are
short enough to bear with interrupt-free execution. Therefore we would
not generally benefit from the preemption disabling feature we are
going to add to the EVL-specific spinlock. Make it a hard lock to
clarify the intent.
