usb: atm: cxacru: fix endpoint checking in cxacru_bind() (CVE-2024-41097)

Summary

usb: atm: cxacru: fix endpoint checking in cxacru_bind()

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved:

usb: atm: cxacru: fix endpoint checking in cxacru_bind()

Syzbot is still reporting quite an old issue [1] that occurs due to
incomplete checking of present usb endpoints. As such, wrong
endpoints types may be used at urb sumbitting stage which in turn
triggers a warning in usb_submit_urb().

Fix the issue by verifying that required endpoint types are present
for both in and out endpoints, taking into account cmd endpoint type.

Unfortunately, this patch has not been tested on real hardware.
