MDEV-17610 Unexpected connection abort after certain operations from within stored procedure

Browse Source 
Always set SERVER_MORE_RESULTS_EXIST when executing stored procedure statements

If statements produce a result, EOF packet needs this flag (SP ends
with an OK packet). IF statetement does not produce a result, affected rows
count are part of the final OK packet.
