orinoco: use dev_err in early initialisation routines

This allows us to use determine_fw_capabilities,
orinoco_hw_read_card_setting and orinoco_hw_allocate_fid prior to
netdev registration.

Since dev_dbg only prints if DEBUG is defined (or dynamic debug is
enabled), move a couple of the more useful prints up to info.
