datapath: #define local_bh_disable to preempt_disable on RT.

We use local_bh_disable() to mean that we don't want to get
preempted or interrupted and normally it covers both situations.
However, on RT kernels local_bh_disable() becomes a no-op because
bottom halves aren't interrupts any more.  We still want the
behavior of disabling preemption so #define them to be the same
on these kernels.
