[LU-13509] Improve ptlrpc_register_bulk() behavior

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.14.0

• Assignee: Chris Horn
• Reporter: Chris Horn

Description

The fix for https://review.whamcloud.com/36309 could be improved a bit. It makes more sense to clear the bd_registered flag in ptlrpc_unregister_bulk() since it is set in ptlrpc_register_bulk().

Also, we can add a test for this bug.
