Subject: [PATCH 5.15 226/262] iavf: Add trace while removing device

From: Jedrzej Jagielski <jedrzej.jagielski@...el.com>

[ Upstream commit bdb9e5c7aec73a7b8b5acab37587b6de1203e68d ]

Add kernel trace that device was removed.
Currently there is no such information.
I.e. Host admin removes a PCI device from a VM,
than on VM shall be info about the event.

This patch adds info log to iavf_remove function.
