Allow retry for Windows account password

[ethanbb]

Description

When configuring SMB shares, entering an incorrect Windows password does not cause a reprompt but instead a generic message "ERROR: SMB share mount failed." The user then has to run fin vm mount to fix the issue. This is just an annoyance.

Steps to reproduce the issue:

1. Be on Windows (WSL, VirtualBox)
2. Run fin system start
3. At the "Enter your Windows account password:" prompt, enter the wrong password.

Describe the results you received:

Enter your Windows account password:
Adding docker SMB share docksal-c...
mount: /c: cannot mount //192.168.64.1/docksal-c read-only.
exit status 32
              Mount command failed... Trying an alternative method...
mount: /c: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.
exit status 32
               ERROR:  SMB share mount failed.
        Make sure your Windows password is correct and run fin vm mount to try again.

Describe the results you expected:

A way to retry entering the password.
