feb082a24a fio: Remove the trim step from full_bench.fio
The test already writes to the entire device twice, so
the trim step does not actually accomplish anything.

7b7799bf9c fio_plugin: switch to LD_PRELOAD instead of dynamically loading
fio has a race between reap_threads() and free_ioengine().  free_ioengine()
will call the ioengine's cleanup routine and then dlclose it if it
is dynamically linked (like the spdk fio plugin).  free_ioengine() does
not set td->io_ops = NULL though until after dlclose() is complete.  If
reap_threads() tries to dereference td->io_ops after our plugin has been
closed but before io_ops was set to NULL, it will segfault.

Solution (until an upstream fio fix is available) is to use LD_PRELOAD
instead.
