Input: iforce - validate number of endpoints before using them

commit 59cf8bed44a79ec42303151dd014fdb6434254bb upstream.

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory that lie beyond the end of the endpoint
array should a malicious device lack the expected endpoints.
