Subject: fix an incorrect IO error reading SMART status
Description: The read SMART status command's return status
 was testing for a success/failure value that included 8
 bits that are "N/A" according to the standard, and required
 that they be zeros.  At least some drives do not fill them
 with zeros, so correct this by masking off the undefined
 bits.
