gspca: konica: add missing endpoint sanity check
commit aa58fedb8c7b6cf2f05941d238495f9e2f29655c upstream.
Make sure to check the number of endpoints to avoid accessing memory
beyond the endpoint array should a device lack the expected endpoints.
Note that, as far as I can tell, the gspca framework has already made
sure there is at least one endpoint in the current alternate setting so
there should be no risk for a NULL-pointer dereference here.

konica chipset using cams")
