Failure in test_dynamic partition movement test

[mmaslankaprv]

This issue tracks failure in the PartitionMovingTest.test_dynamic ducktape test and the partition_moving_test unit test -- sanitizer errors and segfaults here are believed to have the same (as yet undetermined) root cause.

Dynamic test moving partitions failed with the following sanitizer error:

I was able to reproduce this test failure. It triggered UAF error in storage::disk_log_impl
