Subject: kconfig: tristate choice with depender choice

If a tristate choice has another choice dependers, kconfig produce
wrong value.

Example:

choice
	prompt "choice list AB"
config A
	tristate "a"
config B
	tristate "b"
endchoice
choice
	prompt "choice list CD"
	depends on A
config C
       	bool "c"
config D
       	bool "d"
endchoice

kconfig outputs CONFIG_A=m from defconfig with CONFIG_A=y.

This happens if the choice list CD depends on A.
Also, if defconfig contains CONFIG_A=y and "# CONFIG_B is not set",
output is correct.

I found commit a64b44ea ("kconfig: fix tristate choice with minimal
config"), but this problem still exists on v3.3-rc1.  More fix is
needed for choice with dependers?
