Subject: [PATCH v2] thermal: tegra: remove null check for dev pointer

The dev pointer is going through a null check after a dereference.
So this patch removes that useless check since the driver does not
pass a null dev pointer in any case.

Changelog
v2:
 * By following Thierry's comments, changed to remove the null pointer
   check directly and revised the patch subject according.
