gigaset: include cleanup cleanup

Commit 5a0e3ad causes slab.h to be included twice in many of the
Gigaset driver's source files, first via the common include file
gigaset.h and then a second time directly. Drop the spares, and
use the opportunity to clean up a few more similar cases.

Impact: cleanup, no functional change
