MDEV-32682: Assertion `range->rows >= s->found_records' failed in best_access_path

Fix the issue introduced in ec2574fd8f, fix for MDEV-31983:

get_quick_record_count() must set quick_count=0 when it got
IMPOSSIBLE_RANGE from test_quick_select.

Failure to do so will cause an assertion in 11.0, when the number of
quick select rows (0) is checked to be lower than the number of
found_records (which is capped up to 1).
