[PATCH 5/5] examples/dma: fix missing dma close

[Kevin Laatz <kevin.laatz@intel.com>]

The application stops all dmadevs that it used but never closed any,
meaning device cleanup was not done.
This patch adds device cleanup for all dmadevs. All devices need to be
closed for completeness, since devices not used by the application may
also have been created during PCI probe of EAL init.
