[PATCH] usbserial: Fixes use-after-free in serial_open().
If the device is disconnected while serial_open() is executing and
either try_module_get() or the device specific open function fails, the
kref_put() call in the 'bailout_kref_put' label will free the memory
pointed out by 'port'.
The subsequent dereferences in the 'bailout_kref_put' label will be
invalid.
The fix is just to assure kref_put() is called after any 'port' usage.
