Missing error handling in the code of the storage drivers

[tksm]

Describe the bug

We found the following error handlings missing in the code of the storage drivers. Though we've never encountered problems from these in production, I would like to report this just in case.

1. err from clientAPI.ExportRuleList() in reconcileExportPolicyRules().

https://github.com/NetApp/trident/blob/37b01b8ee97fe50d19d7aeeabebb01411a85fb05/storage_drivers/ontap/ontap_common.go#L363-L365

2. err from c.ExportPolicyList() in ExportPolicyGetByName().

https://github.com/NetApp/trident/blob/ad517c448cee0faef3c2c2fe81c81b8ca824264d/storage_drivers/ontap/api/ontap_rest.go#L3407-L3408

Environment

• Trident version: 23.01.1
