cleanup: Select_limit_counters rename set_unlimited to clear
The function was originally introduced by eb0804ef5e7eeb059bb193c3c6787e8a4188d34d
MDEV-18553: MDEV-16327 pre-requisits part 1: isolation of LIMIT/OFFSET handling
set_unlimited had an overloaded notion of both clearing the offset value
and the limit value. The code is used for SQL_CALC_ROWS option to
disable the limit clause after the limit is reached, while at the same
time the calling code suppreses sending of rows.
Proposed solution:
Dedicated clear method for query initialization (to ensure no garbage
remains between executions).
Dedicated set_unlimited that only alters the limit value.
