usb: correct sys.usb.controller sysprop

Browse source 
system/core/init/init.cpp SetUsbController picks the first udc device if
there're multiple udc devices present on the system to populate
sys.usb.controller system property.
CONFIG_USB_DUMMY_HCD enabled in kernel-5.10 GKI would introduce a
dummy udc device named "dummy_udc.0". Depends on timing, the dummy
device might be picked up by the init process and incorrectly populate
sys.usb.controller.
This issue only applies to devices on kernel-5.10 GKI, the WAR is to
overwrite the sysprop if it's incorrectly populated by the dummy udc.
