USB: serial: ir-usb: add missing endpoint sanity check
commit 2988a8ae7476fe9535ab620320790d1714bdad1d upstream.
Add missing endpoint sanity check to avoid dereferencing a NULL-pointer
on open() in case a device lacks a bulk-out endpoint.
Note that prior to commit f4a4cbb2047e ("USB: ir-usb: reimplement using
generic framework") the oops would instead happen on open() if the
device lacked a bulk-in endpoint and on write() if it lacked a bulk-out
endpoint.
Fixes: f4a4cbb2047e ("USB: ir-usb: reimplement using generic framework")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
