Subject: scsi: hpsa: Check for vpd support before sending

Before using vendor-specific VPD pages for getting raid_level and
device_id, check for page support.  If page isn't supported, don't try
to use it.  Also, pay attention to return status on hpsa_get_device_id.

[mkp: fix boolean return warnings reported by kbuild test robot]
