Guangshuo Li 01af542392 usb: ulpi: fix double free in ulpi_register_interface() error path 
When device_register() fails, ulpi_register() calls put_device() on
ulpi->dev.

The device release callback ulpi_dev_release() drops the OF node
reference and frees ulpi, but the current error path in
ulpi_register_interface() then calls kfree(ulpi) again, causing a
double free.

Let put_device() handle the cleanup through ulpi_dev_release() and
avoid freeing ulpi again in ulpi_register_interface().

Fixes: 289fcff4bc ("usb: add bus type for USB ULPI")
