[PATCH] generic/017: skip invalid block sizes for btrfs

[Filipe David Borba Manana <fdmanana@gmail.com>]

In btrfs the block size (called sector size in btrfs) can not be
smaller then the page size. Therefore skip block sizes smaller
then page size if the fs is btrfs, so that the test can succeed
on btrfs (testing only with block sizes of 4kb on systems with a
page size of 4Kb).
