Alexey Khoroshilov 070c0b17f6 USB: cdc-acm: fix double usb_autopm_put_interface() in acm_port_activate()

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.

Found by Linux Driver Verification project (linuxtesting.org).
