Bugzilla Bug 27282

If some cdrom drives run with ide-scsi and some not, it is logical not to use
all_args in /etc/conf.d/hdparm, because hdparm cannot set options on scsi
emulated drives. 
Although not having set all_args, if some drives run with ide-scsi following
warning appears:
Skipping $i hdparm does not support SCSI devices.

The problem is in the following lines in /etc/init.d/hdparm:
elif [ ! -n "${all_args}" ]    # remove ! before -n
then
     ewarn "Skipping $i hdparm does not support SCSI devices."
fi

-n returns true if all_args is NOT empty and ! inverses true to false.
So if ! is removed, the script does what it should do.

Reproducible: Always
Steps to Reproduce:
1. set up some cdrom devices to run with ide-scsi
2. do not set all_args in /etc/conf.d/hdparm
3.

Actual Results:  
Warning "Skipping cdrom1 hdparm does not support SCSI devices." appears,
although it should not.
               


Expected Results:  
No Warning should appear.

as far as i see you are right -> fixed :) (no version bump)
