From Goldwyn Rodrigues <rgoldwyn@suse.de>:
"From earlier discussions, In between errors of a direct I/O cannot
be handled correctly and may need a lot of tracking that it is not
worth performing.
It would be better to drop this test case and add in the documentation
that a direct I/O error could mean that the write() may or may not have
occurred and underlying data may be inconsistent."

Getting an error midway through a direct write would return an error
and the error-code is returned in the write() call. However, partial
data is over-written during the call.
This tests simulates the ENOSPC error to check for partial direct
write consistency.
