[SCSI] arcmsr: Fix hardware wait loops
Remove _interruptible, since receiving a signal while waiting on a
hardware condition will simply cause the driver to busy-wait.
Using msleep_interruptible() is rarely the right thing to do, when
waiting on a hardware condition to change.
Also, replace msleep with ssleep while doing this, where appropriate.
