USB: storage: karma: fix rio_karma_init return

Browse source 
[ Upstream commit b92ffb1edd ]

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: dfe0d3ba20 ("USB Storage: add rio karma eject support")
