From: Andrey Vatoropin <a.vatoro...@crpt.ru>
Static analysis shows that pointer "svms" cannot be NULL because it points
to the object "struct svm_range_list".
Remove the extra NULL check. It is meaningless and harms the readability
of the code.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
