vm: use __func__ for the correct function name

In fee2a2fa39 the KASSERTs in
vm_page_unwire_noq() changed from "vm_page_unwire" to "vm_page_unref".
While the former no longer was part of that function the latter does
not exist as a function and is highly confusing when hit when using
tools to lookup the functions and not doing a full-text search.
Use %s __func__ for printing the function name, as that will do the
right thing as code moves around and functions get renamed.

Hit:	while debugging a wired page leak with linuxkpi/iwlwifi
