crypto: qat - use simple_strtoull to improve qat_uclo_parse_num

Replace the manual string copying and parsing logic with a call to
simple_strtoull() to simplify and improve qat_uclo_parse_num().

Ensure that the parsed number does not exceed UINT_MAX, and add an
approximate upper-bound check (no more than 19 digits) to guard against
overflow.
