MDEV-21342 Assertion in set_ok_status() upon spatial field error on system-versioned table

Browse Source 
SQL_SELECT::check_quick() returns error status only
test_quick_select() returns -1. Fix error handling when lower frames
throw error, but it is ignored by test_quick_select(). Fix return
status for out-of-memory errors which are obviously must be processed
as error in upper frames.
