Paolo Bonzini f1c17521e7 nbd-server: do not exit on failed memory allocation 
The amount of memory allocated in nbd_co_receive_request is driven by the
NBD client (possibly a virtual machine).  Parallel I/O can cause the
server to allocate a large amount of memory; check for failures and
return ENOMEM in that case.
