MDEV-16286 Killed CREATE SEQUENCE leaves sequence in unusable state

Browse Source 
Fixed by deleting the sequence if we where not able to initialize it

I also noticed that we didn't always set the error message when
check_killed(), which could lead to aborted queries without error
beeing properly set. Fixed by default setting error message if
check_error() noticed that killed had been called.
This allowed me to remove a lot of calls to thd->send_kill_message().
