[PATCH 0/4] xfsqa: make some tests work again, add xfs_fsr test

[Dave Chinner]

Enable the growfs test 104 and filter out the useless output, remove
hacks from 073 to do with loop devices and filter the log size out
in 206 to prevent failures with new mkfs binaries that allow large
logs.

Also, add a simple xfs_fsr test to improve coverage in the test
suite.  That's not hard given we have only one test (042) that
defragments only one file.
