MDEV-37302 Assertion failure in Table_triggers_list::add_tables_and_routines_for_triggers upon attempt to insert DEFAULT into non-insertable view

Browse Source 
Only do trigger prelocking for tables that are doing to be
modified (with a write lock). A table can cause prelocking
if its DEFAULT value is used (because DEFAULT can be NEXTVAL),
even if the table itself is only used for reads. Don't process
triggers for such a table
