[PATCH] generic/273: use _get_file_block_size

[Darrick J. Wong]

From: Darrick J. Wong <djwong@kernel.org>

This test calculates the amount of free space on a filesystem and uses
the block size to spread the work of filling the free space among a
bunch of threads.  Unfortunately, the test /should/ be using the
allocation unit size, not the fs block size, which is why this test
fails on configurations such as XFS realtime with a 28k extent size.

NOTE: This patch seems to fix the "porter not complete" problems on
5.16, but not on 5.17-rc1.  However, 5.17-rc1 is totally broken (~72%
failure rate) so I don't think I can count that as a serious QA effort.

Applied and confirmed this fixes generic/273 for realtime 28k
extent sizes for me.
