[PATCH v2] nvmet: replace max(a, min(b, c)) by clamp(val, lo, hi)

[shao.mingyin at zte.com.cn]

From: Li Haoran <li.haoran7 at zte.com.cn>

This patch replaces max(a, min(b, c)) by clamp(val, lo, hi) in the nvme
driver. The clamp() macro explicitly expresses the intent of constraining
a value within bounds, improving code readability.
