scsi: megaraid_sas: remove set but not used variables 'host' and 'wait_time'

Browse Source 
Fixes gcc '-Wunused-but-set-variable' warnings:

drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_suspend:
drivers/scsi/megaraid/megaraid_sas_base.c:7269:20: warning: variable host set but not used [-Wunused-but-set-variable]
drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_aen_polling:
drivers/scsi/megaraid/megaraid_sas_base.c:8397:15: warning: variable wait_time set but not used [-Wunused-but-set-variable]

'host' never used since introduction in commit 31ea708897 ("[SCSI]
megaraid_sas: add hibernation support")

'wait_time' never used since commit 11c71cb4ab ("megaraid_sas: Do
not allow PCI access during OCR")
