scsi: aacraid: Make some symbols static

Fix the following sparse warnings:

drivers/scsi/aacraid/linit.c:867:6: warning:
symbol 'aac_tmf_callback' was not declared. Should it be static?
drivers/scsi/aacraid/linit.c:1081:5: warning:
symbol 'aac_eh_host_reset' was not declared. Should it be static?
drivers/scsi/aacraid/commsup.c:2354:5: warning:
symbol 'aac_send_safw_hostttime' was not declared. Should it be static?
drivers/scsi/aacraid/commsup.c:2383:5: warning:
symbol 'aac_send_hosttime' was not declared. Should it be static?
