The previous fix only let an already-mounted share reconfigure its
decrypt layer — there was still no way to change the mount point or
re-enter credentials for a share that's already set up, since the label
prompt was skipped entirely in that path. Add a real choice when an
existing mount is found: reconfigure the decrypt layer in place (as
before), fully redo the mount (tears down the old one via the new
_vdm_remove_mount and falls through to the normal fresh-mount flow,
label pre-filled from the old one), or skip.
_vdm_remove_mount stops/removes any decrypt-layer systemd unit first
(it sits on top of the CIFS mount), then unmounts, removes the
credentials file, and removes the /etc/fstab tag+entry via a fixed
",+1d" range — the tag line plus exactly the one mount line that always
immediately follows it, not an open-ended range to the next blank line
or EOF (the class of bug fixed earlier in this file's history for the
now-removed remote smb.conf-writing code).
