USB: cdc-acm: fix double usb_autopm_put_interface() in acm_port_activate()
commit 070c0b17f6a1ba39dff9be112218127e7e8fd456 upstream.
If acm_submit_read_urbs() fails in acm_port_activate(), error handling
code calls usb_autopm_put_interface() while it is already called
before acm_submit_read_urbs(). The patch reorganizes error handling code
to avoid double decrement of USB interface's PM-usage counter.
