Fix QByteArray::count implementation for longer data

The issue has been introduced when refactoring QByteArray::count
implementation (see 631127126cc14e7c01cc611532b3256b58785670).

Because the last argument of QByteArrayMatcher::indexIn() method
has a defult value, it has been compiling without issues, but was being
called with incorrect size parameter. Fixed it to pass the length of the
input data correctly.
