devices: vfio: fix clippy warnings

Fix boxed_local, const_static_lifetime, useless_format, and
redundant_closure clippy warnings in the VFIO code.

This fixes all clippy warnings except a single instance of
let_and_return in VfioPciDevice::keep_fds(), since that code is modified
in an upcoming patch.

BUG=None
TEST=./build_test.py
TEST=bin/clippy
