Log Message:
LDT handling fixes:
  - add missing membar_store_store ("membar_producer") when setting a
    new ldt;
  - use UVM_KMF_WAITVA when allocating space for a new ldt instead of
    crashing if uvm_km_alloc fails;
  - if uvm_km_alloc fails in pmap_fork, bail instead of crashing;
  - clarify what else is going on in pmap_fork;
  - don't uvm_km_free while holding a mutex.
