net: wimax/i2400m: fix NULL-deref at probe
[ Upstream commit 6e526fdff7be4f13b24f929a04c0e9ae6761291e ]
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).
Fixes: f398e4240fce ("i2400m/USB: probe/disconnect, dev init/shutdown
and reset backends")
