cherry-pick #18802 to release-4.0


What problem does this PR solve?

Due to the special case for primaryKey in optimistic mode.

tidb/store/tikv/2pc.go

Lines 269 to 276 in bd733c3

if len(c.primaryKey) == 0 {
for i, op := range mutations.ops {
if op != pb.Op_CheckNotExists {
c.primaryKey = mutations.keys[i]
break
}
}
}

The primaryKey may not be the first key of mutations.keys.

What is changed and how it works?

Use batch.isPrimary seems to work correctly.
