Subject: [2.6 patch] scsi/lpfc/: possible cleanups

This patch contains the following possible cleanups:
- make the following needlessly global functions static:
  - lpfc_els.c: lpfc_register_new_vport()
  - lpfc_els.c: lpfc_issue_els_fdisc()
  - lpfc_els.c: lpfc_issue_fabric_iocb()
  - lpfc_els.c: lpfc_fabric_abort_vport()
  - lpfc_hbadisc.c: lpfc_dev_loss_tmo_handler()
  - lpfc_hbadisc.c: lpfc_mbx_cmpl_clear_la()
  - lpfc_hbadisc.c: lpfc_disc_flush_list()
  - lpfc_hbadisc.c: __lpfc_find_node()
  - lpfc_init.c: lpfc_hb_timeout()
  - lpfc_init.c: lpfc_block_mgmt_io()
  - lpfc_sli.c: __lpfc_sli_release_iocbq()
  - lpfc_sli.c: lpfc_sli_next_hbq_slot()
  - lpfc_sli.c: lpfc_sli_hbqbuf_init_hbqs()
  - lpfc_sli.c: lpfc_sli_hbqbuf_find()
  - lpfc_sli.c: __lpfc_sli_issue_iocb()
- #if 0 the following unused global functions:
  - lpfc_els.c: lpfc_fabric_abort_flogi()
  - lpfc_hbadisc.c: lpfc_find_node()
  - lpfc_hbadisc.c: lpfc_findnode_rpi()
- remove the unused exports
