[SCSI] libfc: use offload EM instance again instead jumping to next EM
Vasu Dev [Sat, 13 Mar 2010 00:08:39 +0000 (16:08 -0800)]
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.
