[SCSI] libfc: use offload EM instance again instead jumping to next EM
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.
