    scsi: core: Remove the /proc/scsi/${proc_name} directory earlier

    Remove the /proc/scsi/${proc_name} directory earlier to fix a race
    condition between unloading and reloading kernel modules. This fixes a bug
    introduced in 2009 by commit 77c019768f06 (“[SCSI] fix /proc memory leak in
    the SCSI core”).
