gitk: Fix bug in accessing undefined "notflag" variable

As pointed out by Johannes Sixt and Alexander Gavrilov, commit
2958228430b63f2e38c55519d1f98d8d6d9e23f3 ("gitk: Fix switch statement
in parseviewargs") exposed a latent bug in that $notflag was never
initialized.  Since it isn't used either, this removes it entirely.
