scsi: hisi_sas: Don't create debugfs dump folder twice

Browse Source 
commit 35160421b6 upstream.

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: 7ec7082c57 ("scsi: hisi_sas: Add hisi_sas_debugfs_alloc() to centralise allocation")
