[SCSI] qla2xxx: Code cleanups.



- make the following needlessly global code static:
  - qla_attr.c: qla24xx_vport_delete()
  - qla_attr.c: qla24xx_vport_disable()
  - qla_mid.c: qla24xx_allocate_vp_id()
  - qla_mid.c: qla24xx_find_vhost_by_name()
  - qla_mid.c: qla2x00_do_dpc_vp()
  - qla_os.c: struct qla2x00_driver_template
  - qla_os.c: qla2x00_stop_timer()
  - qla_os.c: qla2x00_mem_alloc()
  - qla_os.c: qla2x00_mem_free()
  - qla_sup.c: qla2x00_lock_nvram_access()
  - qla_sup.c: qla2x00_unlock_nvram_access()
  - qla_sup.c: qla2x00_get_nvram_word()
  - qla_sup.c: qla2x00_write_nvram_word()
- #if 0 the following unused global functions:
  - qla_mbx.c: qla2x00_system_error()
- qla_os.c: remove some unneeded function prototypes
- removed unused functions:
  - qla_dbg.c: qla2x00_dump_pkt()
  - qla_mbx.c: qla2x00_get_serdes_params()
  - qla_mbx.c: qla2x00_get_idma_speed()
  - qla_mbx.c: qla24xx_get_vp_database()
  - qla_mbx.c: qla24xx_get_vp_entry()
