[PATCH] xfstests: fix flink test V2

[Josef Bacik]

I don't have flink support in my xfsprogs, but it doesn't fail with "command not
found" or whatever, it fails because I don't have the -T option, whereas Eric
gets an error about $TEST_DIR being a directory because his xfs_io tries to open
the directory first before it parses the options.  So fix this by checking flink
with these two cases and don't run if we hit either of them.  Thanks,

V1->V2: check for "Is a directory" errors that Eric mentioned, move test up into
the flink specific case.
