DEBUG: fd: make sure we never try to insert/delete an impossible FD number

It's among the cases that would provoke memory corruption, let's add
some tests against negative FDs and those larger than the table. This
must never ever happen and would currently result in silent corruption
or a crash. Better have a noticeable one exhibiting the call chain if
that were to happen.

(cherry picked from commit 9aa324de2d9f69d74f5b30c33a78d3a38501342f)
