DAOS-19059 vos: cache vos object after DTX commit - b28

[Nasf-Fan]

It is unnecessary to evict the vos object from cache after related DTX committed; otherwise, other concurrent modification against the same object shard maybe required to retry.

Steps for the author:

• Commit message follows the guidelines.
• Appropriate Features or Test-tag pragmas were used.
• Appropriate Functional Test Stages were run.
• At least two positive code reviews including at least one code owner from each category referenced in the PR.
• Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

• Gatekeeper requested (daos-gatekeeper added as a reviewer).
