When dma_alloc_coherent() or qla2x00_start_sp() return an error,
the callback function qla2x00_els_dcmd_sp_free in qla2x00_sp_release
will call qla2x00_free_fcport() to kfree fcport. We shouldn't call
qla2x00_free_fcport() again in the error handling path.
Fix this by cleaning up the redundant qla2x00_free_fcport().
