Subject: [PATCH][RESEND]  xfstests: only run generic/300 on filesystems
 supporting

Generic/300 fails when run on a test filesystem that does not support
fallocate(), as in the case of an ext4 filesystem created without the
extent feature.  It uses fio's falloc ioengine to generate part of its
I/O load.

Verify that the test filesystem supports fallocate() before proceeding
with the test.  Also, delete any pre-existing test output to avoid
confusion with old results.
