[PATCH][next] ipv4: remove redundant assignment to n

From: Colin King
Date: Fri May 24 2019 - 18:00:09 EST

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The pointer n is being assigned a value however this value is
never read in the code block and the end of the code block
continues to the next loop iteration. Clean up the code by
removing the redundant assignment.

Addresses-Coverity: ("Unused value")
