scsi: myrs: Make some symbols static

This addresses the following sparse warning:

drivers/scsi/myrs.c:1532:5: warning: symbol 'myrs_host_reset' was not
declared. Should it be static?
drivers/scsi/myrs.c:1922:27: warning: symbol 'myrs_template' was not
declared. Should it be static?
drivers/scsi/myrs.c:2036:31: warning: symbol 'myrs_raid_functions' was
not declared. Should it be static?
drivers/scsi/myrs.c:2046:6: warning: symbol 'myrs_flush_cache' was not
declared. Should it be static?
