fusefrontend: doWrite: delete file header if first write fails
xfstests generic/083 fills the filesystem almost completely while running fsstress in parallel. In fsck, these would show up: readFileID 2580: incomplete file, got 18 instead of 19 bytes This could happen when writing the file header works, but writing the actual data fails. Now we kill the header again by truncating the file to zero.
