So far when prompting for the LUKS passphrase the dialog always looks
like this:

    +------------------------------------------------+
    |           LUKS Passphrase /dev/sdb1            |
    +------------------------------------------------+
    | Enter LUKS passphrase to open /dev/sdb1        |
    | Passphrase:    [                             ] |
    |                                                |
    |                                                |
    |                          [ Cancel ] [ Unlock ] |
    +------------------------------------------------+

Specifically the first line of the dialog says the reason to provide the
passphrase is to open the encryption mapping.  Now the passphrase may
also be requested when resizing the encryption mapping, as part of a
resize of check operation, show the appropriate reason in the password
dialog.

Closes #59 - Resize of LUKS2 encrypted file system fails with "Nothing
             to read on input"
