Subject: [PATCH 5.15 387/846] RDMA/rtrs-clt: Fix the initial value of min_latency

From: Jack Wang <jinpu.wang@...os.com>

[ Upstream commit 925cac6358677d3d64f9b25f205eeb3d31c9f7f8 ]

The type of min_latency is ktime_t, so use KTIME_MAX to initialize the
initial value.

Fixes: dc3b66a0ce70 ("RDMA/rtrs-clt: Add a minimum latency multipath policy")
