[ovs-dev] [PATCH 08/11] ovn-sbctl: Fix possible null pointer to qsort.

[William Tu]

Clang reports possible null pointer 'lflows' passed to qsort.
This is due to the checker unable to make sure whether 'lflows'
gets malloc or not in the previous loop.  Thus, fix it by adding
ovs_assert to pass clang checker.
