A usbnet subdriver must implement the manage_power callback in order
to fully support autosuspend. This allows for the device to be
suspended when there is no active traffic, and USB remote wakeup
is used to signal a resume to the host.
Remove calls to usb_autopm_get/put from rmnet_usb_ctrl_start_rx and
rmnet_usb_ctrl_write_cmd as these functions are only (or should be)
called when the device is already active.

Reads performed on rmnet control devices get blocked on wait queue.
Currently, reads get unblocked only when read response is received
from mdm9x15. Hence during mdm9x15 disconnect unblock reads to return
error to QMI channels.
