Drivers: hv: kvp: check kzalloc return value
kzalloc() return value check was accidentally lost in 11bc3a5fa91f: "Drivers: hv: kvp: convert to hv_utils_transport" commit. We don't need to reset kvp_transaction.state here as we have the kvp_timeout_func() timeout function and in case we're in OOM situation it is preferable to wait.
