Remove superfluous conversion of ippGetLength()'s return value to 'long long'

Both ippGetLength() (CUPS 3) and its predecessor ippLength() (CUPS 2) have always returned size_t, so use the format specifier for that.
Because 'long long' is a signed type that need not have greater width than size_t, this conversion may not do the right thing.
