[PATCH manager 7/7] ui: qga: hide freeze-fs-on-backup check if undefined

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

If the freeze-fs-on-backup key is not explicitly set on the config file
we hide the corresponding checkbox and hint.

Note that when the checkbox is unchecked we delete the value from the
config resulting.
