usbip: Correct format specifier for seqnum from %d to %u

JIRA: https://issues.redhat.com/browse/RHEL-78931

commit 81702d4
Author: Xiong Nandi <xndchn@gmail.com>
Date: Wed, 1 Jan 2025 00:15:38 +0800

  The seqnum field in USBIP protocol is an unsigned value.
  So we fix the format specifier from %d to %u to correctly
  display the value.
