[PATCH 3/5] generic/091: enable sub-block reads

[Christoph Hellwig <hch@lst.de>]

The description of generic/091 claims that it tries to exercise sub-block
direct I/O, but the test currently limits reads to PAGE_SIZE alignment.

Use the new min_dio_alignment -r option to query the minimal read
alignment and only limit the read alignment to that.
