Subject: udf: Fix detection of VAT version
X-Git-Tag: v2.6.26-rc1~1108^2~8

udf: Fix detection of VAT version

We incorrectly (way to strictly) checked version of VAT on loading and thus
refuse to mount correct media.  There are just two format versions - below 2.0
and above 2.0 and we understand both. So update the version check accordingly.
