[PATCH 4/5] xkbscan: resolve build warning/rpmlint error

[Jan Engelhardt]

xkbscan.l: In function 'setScanState':
xkbscan.l:201:1: warning: control reaches end of non-void function
I: Program returns random data in a function
E: libxkbcommon no-return-in-nonvoid-function xkbscan.l:201

Change return type of setScanState to void, since a return value is
never used by its callers.
