[U-Boot] [BUG] cmd : Local Hush Variable Could not be deleted

You cannot.  Local variables can be set to an empty value, but they
cannot be deleted.

Note that there is no functional difference between a non-existing
local variable and one with an empty value anyway.  Same as in other
shells.

Best regards,

Wolfgang Denk
