	src/sys/arch/xen/xen: xbd_xenbus.c

Log Message:
- Add a missing UVM_KMF_WIRED to uvm_km_alloc(), this would trigger an
 assertion in uvm
- xbd_open(): check that the device exists before calling dk_open(). Fix
 a null pointer dereference when trying to open a unconfigured xbd.
Should fix 2 issues reported by Stephane Bortzmeyer on port-xen.
