xfsprogs (mainly mkfs) is using the logical sector size of a volume to initialize
the filesystem, which, even in devices using Advanced Format, it can get a 512
bytes sector size if it is set as the logical sector size.
This patch changes the ioctl to get the physical sector size, independent of the
logical size.
