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: simplify wlockMap
...
mapMutex can be anonymous and using an RWMutex is overkill
because the lock protects very short sections.

Encrypt path in statfs() calls
...
Paths in statfs() calls were not encrypted resulting in
an Function not implemented error, when the unencrypted
path didn't exist in the underlying (encrypted)
filesystem.
$ df plain/existingdir
df: ‘plain/existingdir’: Function not implemented

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.
