Description

Patrick did a test run in teuthology that showed a bunch of failed async creates:

[  911.040357] ceph: ceph: async create failure path=(1)splitdir/file_152 result=-28!
[  911.048080] ceph: ceph_async_create_cb: no req->r_target_inode for 0x10000000099

-28 is -ENOSPC. Later, the umount hung and the debugging patch we had in place captured this:

[  986.329589] ceph: 10000000099:fffffffffffffffe Fw 312 0 0

The client is trying to flush caps for a file that failed to be created. If an async create fails, then we must purge any caps for it as well.

Closing as duplicate of #51279, as cleaning these up is just part of what's needed to fix that issue.
