networking: add missing brackets

Our codestyle demands having brackets also around if-blocks made up
by one line only.

In patch "networking: add and implement net_addr_ll_set() API" this
rule was not respected and a new one-line-if-block was added with no
brackets.

Fix this by adding the related brackets as needed.
