[PATCH] generic/451: check the return when create overlong file name

[PATCH] generic/451: check the return when create overlong file name

[XiaoLi Feng]

From: xiaoli feng <xifeng@redhat.com>

When create overlong file name, it's expected to return
ENAMETOOLONG. But it returns ENOENT in filesystem cifs. It also
should be tested in all general filesystems. So add it into
generic test.

+# Check if it returns correct message when create MAXNAMELENGTH file.
+# The filesystem cifs have the issue about returning the wrong error
+# message. And checking the issue is similarly suiting for general 
+# filesystems. So I add it into generic test.
