usb: storage: Drop unused fields in struct us_data
Only bulk-only transport is supported by the currennt codebase, so
ep_bInterval and recv_intr_ep are not really used. Remove them and all
related code. While at it remove flags and subclass as well since they
are not really used anywhere in the codebase.
