Input: pegasus_notetaker - fix endpoint sanity check
commit bcfcb7f9b480dd0be8f0df2df17340ca92a03b98 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.
Fixes: 1afca2b66aac ("Input: add Pegasus Notetaker tablet driver")
