[ Upstream commit 35160421b63d4753a72e9f72ebcdd9d6f88f84b9 ]
Due to a merge error, we attempt to create 2x debugfs dump folders, which
fails:
[ 861.101914] debugfs: Directory 'dump' with parent '0000:74:02.0'
already present!
This breaks the dump function.
To fix, remove the superfluous attempt to create the folder.
Fixes: 7ec7082c57ec ("scsi: hisi_sas: Add hisi_sas_debugfs_alloc() to centralise allocation")
