nbd: Rename NBDRequest to NBDRequestData

We have both 'struct NBDRequest' and 'struct nbd_request'; making
it confusing to see which does what.  Furthermore, we want to
rename nbd_request to align with our normal CamelCase naming
conventions.  So, rename the struct which is used to associate
the data received during request callbacks, while leaving the
shorter name for the description of the request sent over the
wire in the NBD protocol.
