[PATCH] usb: Replace a < b ? a : b construct with min_t(type, a, b) in adutux driver

[dmg@turingmachine.org]

From: Daniel M German <dmg@turingmachine.org>

Use min_t to find the minimum of two values instead of using the ?: operator.

We use min_t instead of min to avoid the compilation warning 'comparison of
distinct pointer types lacks a cast'.

This change does not alter functionality. It is merely cosmetic intended to
improve the readability of the code.
