ser_gigaset: remove unnecessary kfree() calls from release method

Browse source 
commit 8aeb3c3d655e22d3aa5ba49f313157bd27354bb4 upstream.

device->platform_data and platform_device->resource are never used
and remain NULL through their entire life. Drops the kfree() calls
for them from the device release method.
