usb: dwc2: platform: Improve error reporting for problems during .remove()
[ Upstream commit 55f223b8b408cbfd85fb1c5b74ab85ccab319a69 ]
Returning an error value in a platform driver's remove callback results in
a generic error message being emitted by the driver core, but otherwise it
doesn't make a difference. The device goes away anyhow.
For each case where ret is non-zero the driver already emits an error
message, so suppress the generic error message by returning zero
unconditionally. (Side note: The return value handling was unreliable
anyhow as the value returned by dwc2_exit_hibernation() was overwritten
anyhow if hsotg->in_ppd was non-zero.)
