[PATCH] checkout: squelch "'mode' may be used uninitialized in this function" warning

[dsp@php.net]

From: David Soria Parra <dsp@php.net>

Use a 'fake' initialization for the 'mode' variable to work around a
GCC warning as in 5a7a367. The necessary condition to initialize 'mode'
will always be true but cannot be checked by the compiler.
