PCI: Free released resource after coalescing
commit 8ec9c1d5d0a5a4744516adb483b97a238892f9d5 upstream.
release_resource() doesn't actually free the resource or resource list
entry so free the resource list entry to avoid a leak.
Closes: https://lore.kernel.org/r/878r9sga1t.fsf@kernel.org/
Fixes: e54223275ba1 ("PCI: Release resource invalidated by coalescing")
