It sounds like you don't want routing for this vlan to occur on the EX. If that is the case, you should simply delate the layer 3 RVI (routed vlan interface). They are only created when you do want routing to occur on the switch.
On the SRX connections, I assume these are here for redundancy since the two switches are in a VC. The VC should be treated as a single switch so I assume the reason you are creating the two connections is for failover redundancy in the event of issues. If so, the more typical SRX configuration would be:
Create a reth interface and make both physical interfaces a member
Delete the vlan RVI and VLAN
Create the layer three address and vlan tag on the reth interface unit 89
