Nirbhay Choubey 978c2a37c0 MDEV-7640: CHANGE MASTER TO doesn't work with prepared statements
When CHANGE MASTER was executed as a PS, its attributes were wrongly
getting reset toward the end of PREPARE. As a result, the subsequent
executions had no effect. Fixed by making sure that the CHANGE MASTER
attributes are preserved during the lifetime of the PS.
