GPU-DRM-GMA500: Delete unnecessary checks before two function calls

Browse source 
The functions pci_dev_put() and psb_intel_i2c_destroy() test whether
their argument is NULL and then return immediately.
Thus the tests around their calls are not needed.

This issue was detected by using the Coccinelle software.
