scsi: megaraid_sas: max_fw_cmds are decremented twice, remove duplicate 

Fix to account for the reply_q_sz not exceeding the maximum commands
that the firmware can support, instance->max_fw_cmds is already
decremented in megasas_fusion_update_can_queue().  Remove the extra
decrement logic in code.
