Christian Schwarz 434af3771d drop layer map lock before removing droppen popped frozen layer ...

This is a shot in the dark to fix the pageserver deadlock
described in https://github.com/neondatabase/neon/issues/3712

The ASCII art in the comment added in this commit describes a potential
deadlock that involves page cache and EphemeralFile.
So, I guess it's a useful change by itself.

But, I can't find a scenario with the current code base where
we would actually arrive in the described deadlock.

Let's see whether the deadlock from #3712 still reproduces with this
fixx. I can't repro it locally.
