net: usb: pegasus: validate USB endpoints

Browse source

commit 11de1d3ae5 upstream.

The pegasus driver should validate that the device it is probing has the
proper number and types of USB endpoints it is expecting before it binds
to it.  If a malicious device were to not have the same urbs the driver
will crash later on when it blindly accesses these endpoints.
