Joe Hattori dcd4de31bd usb: chipidea: ci_hdrc_imx: decrement device's refcount in .remove() and in the error path of .probe() ...

commit 74adad500346fb07d69af2c79acbff4adb061134 upstream.

Current implementation of ci_hdrc_imx_driver does not decrement the
refcount of the device obtained in usbmisc_get_init_data(). Add a
put_device() call in .remove() and in .probe() before returning an
error.

This bug was found by an experimental static analysis tool that I am
developing.
