[PATCH 1/1] IB/rxe: Remove redudant variable rxe

[Zhu Yanjun <yanjun.zhu@xxxxxxxxxx>]

After the commit ("IB/rxe: Simplify rxe_find_route() to
avoid GID query for netdev"), in the functions rxe_prepare,
prepare4 and prepare6, the variable rxe is not needed.

Fix: commit ("IB/rxe: Simplify rxe_find_route() to avoid GID
	      query for netdev")
