Subject: [PATCH 1/4] Revert "staging: r8712u: Tracking kmemleak false positives."

This reverts commit 5d3da4a20a271e3cf5496a50cbb8118aa019374f.

This commit annotated false positive for kmemleak. The reasoning is that
the buffers are freed when the driver is unloaded. However, there is
actually potential memory leak when probe fails.
