[netmap] fix locking regressions

* Firmware oriented NICs may need to sleep in their configuration paths.
  Use RLOCK instead of WLOCK to allow this to again occur.

  This fixes netmap on cxgbe.

* Change the worker lock to a normal mutex rather than a spin lock.
  Drivers shouldn't be doing netmap work from the fast interrupt
  handlers, so it's not required to be a spinlock.
