hpsa: correct skipping masked peripherals
The SA controller spins down RAID drive spares.
A REGNEWD event causes an inquiry to be sent to all physical
drives. This causes the SA controller to spin up the spare.
The controller suspends all I/O to a logical volume until
the spare is spun up. The spin-up can take over 50 seconds.
This can result in one or both of the following:
- SML sends down aborts and resets to the logical volume
and can cause the logical volume to be off-lined.
- a negative impact on the logical volume's I/O performance
each time a REGNEWD is triggered.
