[PATCH 12/14] GPU-DRM-TTM: Less function calls in ttm_dma_pool_init() after error detection

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Thu, 22 Sep 2016 17:30:52 +0200

The kfree() function was called in up to two cases
by the ttm_dma_pool_init() function during error handling
even if the passed variable contained a null pointer.

Adjust jump targets according to the Linux coding style convention.
