Subject: [PATCH 2/2] hpsa: make device attrs static

No need to export those device attributes.

In fact, without this patch, we can trip over a build error if hpsa
is a built-in and another driver also declares and exports attributes
with the same name.

You'll see errors like:

	drivers/scsi/built-in.o: multiple definition of `dev_attr_lunid'
	drivers/block/built-in.o: first defined here
