net: wimax/i2400m: fix NULL-deref at probe
Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory beyond the endpoint array should a malicious device lack the expected endpoints. The endpoints are specifically dereferenced in the i2400m_bootrom_init path during probe (e.g. in i2400mu_tx_bulk_out).
