remove duplicated check of device path in aws attacher

**What this PR does / why we need it**:

The `devicePath` parameter is already validated in this [code](b7100f1ee7/pkg/volume/aws_ebs/attacher.go (L158)), so no need to check it again in the `for loop` as it won't be modified.

This can make the code clearer.

**Release note**:
