Dmitry Shulga 70807d1473 Fixed bug #55421 - Protocol::end_statement(): Assertion `0' on ...

multi-table UPDATE IGNORE.
The problem was that if there was an active SELECT statement
during trigger execution, an error risen during the execution
may cause a crash. The fix is to temporary reset LEX::current_select
before trigger execution and restore it afterwards. This way
errors risen during the trigger execution are processed as
if there was no active SELECT.
