scsi: target: drop unused pi_prot_format attribute storage 

On write, the pi_prot_format configfs attribute invokes the device
format_prot() callback if present. Read dumps the contents of
se_dev_attrib.pi_prot_format which is always zero.  Make the configfs
attribute write-only, and drop the always zero se_dev_attrib.pi_prot_format
storage.
