PATCH 1/1 scsi/qla2xxx/: possible cleanups

This patch contains the following possible 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_dbg.c: qla2x00_dump_pkt()
- qla_mbx.c: qla2x00_system_error()
- 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()
- qla_os.c: remove some unneeded function prototypes
