RHELMISC-7213: Fix share folder handle_exceptions

Fix retry behavior in handle_exceptions when share_folder fails.
Previously, when share_folder failed, handle_exceptions would retry
the entire block, attempting to create an already existing folder.
This led to unnecessary retries and potential errors.

Now the operations are separated:
- Folder creation has its own exception handling block
- Share folder and link generation are handled separately
- Prevents redundant folder creation attempts during retries

This ensures cleaner retry logic and proper error handling for
each operation independently.
