Amy 0f60cad6bd network: fix line break issues 
Commit 5e0fc5c1 ("network: prevent crash by disconnecting device")
introduced two new line breaks after the final call of
remove_wifi_device. Those line breaks are unnecessary, as pointed out by
Robert (@robert.ancell). They should be removed for the MR to be merged.

This patch removes those line breaks, which should allow for !1359 to be
properly merged.
