[Bug](materialized-view) Fixed the problem of using drop table force and
create mv stmt at the… (#41580)
… same time causing fe startup failure.
## Proposed changes
Fixed the problem of using drop table force and create mv stmt at the
same time causing fe startup failure.
Consider this scenario：
create mv -> drop table force -> create mv stmt cancelled
At this time there is a checkpoint like this：
[---------checkpoint---------] [-------- editlog--------]
create mv -> drop table force -> create mv stmt cancelled
In this case, when read meta and parse create mv stmt, it will fail
because there is no corresponding table, further causing fe startup
failure.
