[PATCH 2/2] xfstests: split mapped writes vs direct I/O tests from 091

[Christoph Hellwig]

This effectively reverts

	xfstests: add mapped write fsx operations to 091

and adds a new test case for it.  It tests something slightly different, and
regressions in existing tests due to new features are pretty nasty in a
test suite.
