[PATCH 13/16] libfc: use offload EM instance again instead jumping to next EM

[Robert Love <robert.w.love@intel.com>]

From: Vasu Dev <vasu.dev@intel.com>

Since use of offloads is more efficient than switching
to non-offload EM. However kept logic same to call em_match
if it is provided in the list of EMs.

Converted fc_exch_alloc to inline being now tiny a function
and already not an exported libfc API any more.
