[PATCH] ui/ncurses: Prevent crash if bd->image NULL

[Samuel Mendoza-Jonas]

The discover server can pass boot options with no actual
boot data if parsing conf files such as:

label Dummy entry

label Rexec petitboot latest
	kernel tftp://host/petitboot/vmlinux
	initrd tftp://host/petitboot/rootfs.cpio.xz

Which leads to a boot_editor crash when comparing mountpoints.
We might still want to allow blank fields in boot entries,
so check for bd->image before searching sysinfo
