[LTP] [PATCH 3/3] file_attr02: Simplify device mounting

[Martin Doucha]

The file_attr02 test creates an XFS partition with reflinks enabled.
However, some kernels cannot mount such partitions so the test
needs to check kernel support. The LTP library can now do the check
internally so use this feature instead of mounting explicitly in setup().
