[PATCH v1] usb: gadget: udc: cdns2: Simplify with dev_err_probe()

[Yan Zhen <yanzhen@vivo.com>]

Use dev_err_probe() to simplify the error path and unify a 
message template.

Using this helper is totally fine even if err is known to never 
be -EPROBE_DEFER.

The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.
