[Patch] xfsqa: 091 needs to support sector size != 512 bytes

[David Chinner <dgc@sgi.com>]

Test 091 assumes a direct I/O alignment of 512 bytes,
a hold over from 2.4 kernels. On 2.6. kernels, direct
I/O needs to be aligned to the sector size the filesystem
was mkfs'd with.

Teach 091 about 2.6 kernels and grab the sector size from the
xfs_info output.
