Dongliang Mu 7eb2bf8714 usb: misc: usb3503: call clk_disable_unprepare in the error handling ...

Smatch reports the following warning:

drivers/usb/misc/usb3503.c:267 usb3503_probe() warn: 'hub->clk'
from clk_prepare_enable() not released on lines: 240,246,252

Fix this by adding a flag to indicate if hub->clk is prepared or not
and invoke clk_disable_unprepare in the error handling.
