[PATCH] generic/095: don't silence fio error output

[Zorro Lang <zlang@redhat.com>]

This case print both fio stdout and stderr to .full file, that cause
we miss some unexpected failures when there's a bug. For example:

  file:io_u.c:1803, func=io_u error, error=Block device required

This's an regression issue we find on a downstream kernel, not in
upstream. So release unexpected fio error output to find more issues.
