fuse: don't block in fuse_get_dev() for non-sync_init case

Browse source

Commit a8dd5f1b73 ("fuse: create fuse_dev on /dev/fuse open instead of
mount") changed behavior so that fuse_get_dev() now unconditionally
blocks waiting for a connection, even in the case where sync_init was
not set. Previously, non-sync_init opens returned -EPERM immediately.

Restore the previous behavior of returning -EPERM.
