Mark Johnston 8ddb5aff83 netmap: Fix error handling in nm_os_extmem_create() 
We bump the object reference count prior to mapping it into the kernel
map, at which point the vm_map_entry owns the reference.  Then, if
vm_map_wire() fails, vm_map_remove() will release the reference, so we
should avoid decrementing it in the error path.
