[PATCH -next] pm8001: remove set but not used variables 'param, sas_ha'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/pm8001/pm8001_hwi.c: In function 'mpi_smp_completion':
drivers/scsi/pm8001/pm8001_hwi.c:2901:6: warning:
 variable 'param' set but not used [-Wunused-but-set-variable]

drivers/scsi/pm8001/pm8001_hwi.c: In function 'pm8001_bytes_dmaed':
drivers/scsi/pm8001/pm8001_hwi.c:3247:24: warning:
 variable 'sas_ha' set but not used [-Wunused-but-set-variable]

They're never used since introduction, so can be removed.
