Details:

Hi,
in GRUB configuration there can exist the 2 following situations:
submenu AAA {
    menuentry BBB {
    }
}
or:
menuentry AAA {
    menuentry BBB {
    }
}
In the latter situation, the inner menuentry statement should first unset
variable chosen, otherwise saved_entry from GRUB environment block will not
work as expected.
