iavf: Add trace while removing device

BugLink: https://bugs.launchpad.net/bugs/1964361
[ 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.
