Mathias Kresin b35a41c139 generic: backport dwc2 kernel panic fix
In case the soft reset in dwc2_core_reset() timeouts, the
hsotg->core_params are freed albeit it is owned by the core. This
results into a kernel panic as shown in FS#351.

Subject: [PATCH] usb: dwc2: Remove unnecessary kfree
This shouldn't be freed by the HCD as it is owned by the core and
allocated with devm_kzalloc.
