usb: fotg210-hcd: Fix an error message

[ Upstream commit a60a343 ]

'retval' is known to be -ENODEV here.
This is a hard-coded default error code which is not useful in the error
message. Moreover, another error message is printed at the end of the
error handling path. The corresponding error code (-ENOMEM) is more
informative.

So remove simplify the first error message.

While at it, also remove the useless initialization of 'retval'.
