common/blkdev: collect non-SMART data too

Browse Source 
Call smartctl with -x instead of -a:

       -a, --all
              Prints  all SMART information about the disk, or TapeAlert infor‐
              mation about the tape drive or changer.  For ATA devices this  is
              equivalent to
              '-H -i -c -A -l error -l selftest -l selective'
              and for SCSI, this is equivalent to
              '-H -i -A -l error -l selftest'.
              For NVMe, this is equivalent to
              '-H -i -c -A -l error'.
              Note  that  for  ATA  disks  this  does  not enable the non-SMART
              options and the SMART options which require  support  for  48-bit
              ATA commands.

vs

       -x, --xall
              Prints all SMART and non-SMART information about the device.  For
              ATA devices this is equivalent to
              '-H -i -g all -g wcreorder -c -A  -f  brief  -l  xerror,error  -l
              xselftest,selftest -l selective -l directory -l scttemp -l scterc
              -l devstat -l defects -l sataphy'.
              and for SCSI, this is equivalent to
              '-H -i -g all -A -l error -l selftest -l background -l sasphy'.
              For NVMe, this is equivalent to
              '-H -i -c -A -l error'.
