DAOS-16575 rebuild: set rgt DRS_COMPLETED for unretryable failure

[liuxuezhao]

If rebuild failed with unretryable failure, set it as DRS_COMPLETED to avoid following pool query always report rebuild busy such as - Rebuild failing (state=busy, status=-2001)
after this patch, that kind of failed rebuild will report - Rebuild failed (state=done, status=-2001)
This can fix test_rebuild_31/REBUILD31 problem.

For test_rebuild_32/REBUILD32 add DAOS_POOL_TGT_UPDATE_SKIP_RF_CHECK to bypass DAOS_POOL_RF checking when changing pool map.
