scsi: aic94xx: Pass gfp_t flags to libsas event notifiers

Browse Source 
Use the new libsas event notifiers API, which requires callers to
explicitly pass the gfp_t memory allocation flags.

Context analysis:

  aic94xx_hwi.c: asd_dl_tasklet_handler()
    -> asd_ascb::tasklet_complete()
    == escb_tasklet_complete()
      -> aic94xx_scb.c: asd_phy_event_tasklet()
      -> aic94xx_scb.c: asd_bytes_dmaed_tasklet()
      -> aic94xx_scb.c: asd_link_reset_err_tasklet()
      -> aic94xx_scb.c: asd_primitive_rcvd_tasklet()

All functions are invoked by escb_tasklet_complete(), which is invoked by
the tasklet handler. Pass GFP_ATOMIC.
