Incorrect Storage Size for NVMe

[nchizhov]

Using version 2.6

When try to get storage size of NVMe disk - it's return 0.

Problem in hdparm - it's return incorrect data for NVMe disks. If I try to comment^

for my $k (qw(MODEL FIRMWARE SERIALNUMBER DISKSIZE)) {
     $storage->{$k} = $info->{$k} if defined $info->{$k};
}

disk size returned correct disksize.
