[SPARK-26264][CORE]It is better to add @transient to field 'locs' for class
`ResultTask`.
## What changes were proposed in this pull request?
The field 'locs' is only used in driver side for class `ResultTask`, so it
is not needed to serialize when sending the `ResultTask` to executor.
Although it's not very big, it's very frequent, so we can add` transient`
for it like `ShuffleMapTask`.
## How was this patch tested?
Existed unit tests
