[PATCH] IB/mlx5: Remove dead code from alloc_cached_mr()

[Roland Dreier <roland-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Roland Dreier <roland-BHEL68pLQRGGvPXPguhicg@public.gmane.org>

The only place that assigns mr inside the loop already does a break.
So "if (mr)" will never be true here since the function initializes mr
to NULL at the top.  We can just drop the extra if and break here.
