[PATCH 4.9 060/117] usb: dwc3: core: add phy cleanup for probe error handling

[Greg Kroah-Hartman]

From: Li Jun <jun.li@xxxxxxx>

commit 03c1fd622f72c7624c81b64fdba4a567ae5ee9cb upstream.

Add the phy cleanup if dwc3 mode init fail, which is the missing part of
de-init for dwc3 core init.

Fixes: c499ff71ff2a ("usb: dwc3: core: re-factor init and exit paths")
