[ccan] [PATCH v2 07/13] configurator: Fix compiler warning with compare

[Kevin Locke]

Visual Studio prints warning C4706 "assignment within conditional
expression" when there is an assignment without a comparison in a
conditional expression.  Therefore, to silence the warning, add an
explicit comparison.
