Masahiro Yamada d67624d814 kconfig: improve error message for recursive dependency in choice
Kconfig detects recursive dependencies in a choice block, but the error
message is unclear.

[Test Code]

    choice
            prompt "choose"
            depends on A

    config A
            bool "A"

    config B
            bool "B"

    endchoice

[Result]

    Kconfig:1:error: recursive dependency detected!
    Kconfig:1:      choice <choice> contains symbol A
    Kconfig:5:      symbol A is part of choice <choice>
    For a resolution refer to Documentation/kbuild/kconfig-language.rst
    subsection "Kconfig recursive dependency limitations"

The phrase "contains symbol A" does not accurately describe the problem.
The issue is that the choice depends on A, which is a member of itself.

The first if-block does not print a sensible message. Remove it.

This commit improves the error message to:

    Kconfig:1:error: recursive dependency detected!
    Kconfig:1:      symbol <choice> symbol is visible depending on A
    Kconfig:5:      symbol A is part of choice <choice>
    For a resolution refer to Documentation/kbuild/kconfig-language.rst
    subsection "Kconfig recursive dependency limitations"
