NFS/pNFS: Don't call pnfs_free_bucket_lseg() before removing the request
In pnfs_generic_clear_request_commit(), we try calling pnfs_free_bucket_lseg() before we remove the request from the DS bucket. That will always fail, since the point is to test for whether or not that bucket is empty. Fixes: c84bea59449a ("NFS/pNFS: Simplify bucket layout segment reference counting") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
