nbd: Don't use *_to_cpup() functions
The *_to_cpup() functions are not very useful, as they simply do
a pointer dereference and then a *_to_cpu(). Instead use either:
* ld*_*_p(), if the data is at an address that might not be
correctly aligned for the load
* a local dereference and *_to_cpu(), if the pointer is
the correct type and known to be correctly aligned
