Johan Hovold 21aa01da9d Input: pegasus_notetaker - fix endpoint sanity check
commit bcfcb7f9b4 upstream.

The driver was checking the number of endpoints of the first alternate
setting instead of the current one, something which could be used by a
malicious device (or USB descriptor fuzzer) to trigger a NULL-pointer
dereference.
