USB: mos7840: fix port-device leak in error path
commit 3eb55cc4ed88eee3b5230f66abcdbd2a91639eda upstream.
The driver set the usb-serial port pointers to NULL on errors in attach,
effectively preventing usb-serial core from decrementing the port ref
counters and releasing the port devices and associated data.
