Fixes gcc '-Wunused-but-set-variable' warnings:
drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_fw_crash_buffer_show:
drivers/scsi/megaraid/megaraid_sas_base.c:3138:16: warning: variable buff_addr set but not used [-Wunused-but-set-variable]
drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_get_pd_list:
drivers/scsi/megaraid/megaraid_sas_base.c:4426:13: warning: variable ci_h set but not used [-Wunused-but-set-variable]
'buff_addr' is never used since inroduction in
commit fc62b3fc9021 ("megaraid_sas : Firmware crash dump feature support")
'ci_h' is not used since commit 9b3d028f3468 ("scsi: megaraid_sas:
