Handling the continue cases for BDS retry (#367)

## Description

The original change (#347)
will not handle the use case when the last entry in the BootOptions
being inactive, and the loop will break in one of the "continue" cases.

This change will ensure that continue statements redirect control to
logic for handling infinite retry attempt support.

Fixes #368.
