### What problem does this PR solve?
Problem Summary:
DeletePredicatePB should be DeleteSubPredicatePB.
Test case is too ambiguous to add, since this bug is triggered by a huge
random test and failed to find the minimal case. However, this fix is
verified under the wild test that it does works.
Note that this problem may be triggered by another bug, cuz schema in
delete predicate rowset should contain column referred in delete
condition. Even if we don't have this fix, this error should never
happend.
But this error occurred under wild tests, means that schema in delete
predicate rowset is not adaptable with delete condition. I think it is
under some status that delete operation use BE tablet schema rather than
schema from FE, and the former rename operation result in that status.
But I failed to add a test case to reproduce, and think that by no way
will it happend occurding to the related code.
