[PATCH] diff: remove another ternary expression always evaluating to true

[Stefan Beller <stefanbeller@googlemail.com>]

The condition before the changed line dereferences 'one' to query the mode,
so if the condition evaluates to true, the variable one must not be null.
Therefore we do not need the ternary operator depending on one, giving
either one->path or two->path. This always evaluates to one->path, so
we can remove the ternary operator.

The condition and the usage of the ternary operator have been introduced
by the same commit (752c0c24, 2009-10-19, Add the --submodule option to
the diff option family). As that commit message refers to a GitTogether
I'd assume that patch was crafted in a hurry, so maybe overlooking the
need for a ternary operator there.
