BUG/MAJOR: poller: drop FD's tgid when masks don't match

A bug was introduced in 2.7-dev2 by commit 1f947cb39 ("MAJOR: poller:
only touch/inspect the update_mask under tgid protection"): once the
FD's tgid is held, we would forget to drop it in case the update mask
doesn't match, resulting in random watchdog panics of older processes
on successive reloads.

This should fix issue #1798. Thanks to Christian for the report and
to Christopher for the reproducer.

No backport is needed.
