[PATCH v2 for-7.1 6/9] nbd: code motion and function renaming

[Paolo Bonzini]

Prepare for the next patch, so that the diff is less confusing.

nbd_client_connecting is moved closer to the definition point.

nbd_client_connecting_wait() is kept only for the reconnection
logic; when it is used to check if a request has to be reissued,
use the renamed function nbd_client_will_reconnect().  In the
next patch, the two cases will have different locking requirements.
