[PATCH -next] scsi: hisi_sas: Make three functions static

[YueHaibing]

Fix sparse warnings:

drivers/scsi/hisi_sas/hisi_sas_main.c:3686:6:
 warning: symbol 'hisi_sas_debugfs_release' was not declared. Should it be static?
drivers/scsi/hisi_sas/hisi_sas_main.c:3708:5:
 warning: symbol 'hisi_sas_debugfs_alloc' was not declared. Should it be static?
drivers/scsi/hisi_sas/hisi_sas_main.c:3799:6:
 warning: symbol 'hisi_sas_debugfs_bist_init' was not declared. Should it be static?
