USB: storage: karma: fix rio_karma_init return
The function rio_karam_init() should return -ENOMEM instead of
value 0 (USB_STOR_TRANSPORT_GOOD) when allocation fails.
Similarly, it should return -EIO when rio_karma_send_command() fails.
Fixes: dfe0d3ba20e8 ("USB Storage: add rio karma eject support")
