openvswitch: Use kmalloc_size_roundup() to match ksize() usage
[ Upstream commit ab3f7828c9793a5dfa99a54dc19ae3491c38bfa3 ]
Round up allocations with kmalloc_size_roundup() so that openvswitch's
use of ksize() is always accurate and no special handling of the memory
is needed by KASAN, UBSAN_BOUNDS, nor FORTIFY_SOURCE.
