fusefrontend: replace unreliable "fd < 0" check
...
... with the "released" boolean.
For some reason, the "f.fd.Fd() < 0" check did not work reliably,
leading to nil pointer panics on the following wlock.lock().
The problem was discovered during fsstress testing and is unlikely
to happen in normal operations.
With this change, we passed 1700+ fsstress iterations.

fusefrontend: use sync.Once for one-time warnings
...
Using a simple boolean was racy (which was harmless
in this case) and non-idomatic.

fusefronted: check Fstat return value on file create
...
The Fstat call should never fail, but still, if it does return an error
it should be handled properly.

fusefrontend: fix panic due to concurrently unregistered wlock
...
Commit 730291feab properly freed wlock when the file descriptor is
closed. However, concurrently running Write and Truncates may
still want to lock it. Check if the fd has been closed first.

fusefrontend: fix wlock memory leak
...
The write lock was not freed on release, causing a slow memory leak.
This was noticed by running extractloop.bash for 10 hours.
