[PATCH -next] scsi: megaraid_sas: remove set but not used variable 'cur_state'

[YueHaibing]

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

drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_transition_to_ready:
drivers/scsi/megaraid/megaraid_sas_base.c:3900:6: warning: variable cur_state set but not used [-Wunused-but-set-variable]

It's not used any more since commit 7218df69e360 ("[SCSI]
megaraid_sas: use the firmware boot timeout when waiting for commands")
