Bug #29307: status.test fails with different Table_locks_immediate

When using --log --log-output=table, we increment Table_locks_immediate
with every query.  The wait_condition.inc runs a query a variable number
of times, depending on server load, etc.  This is a problem, when the
test is checking the Table_locks_immediate value.

Fix is to adjust the Table_locks_immediate value based on how many times
the wait_condition query was executed.
