fusefs: recycle vnodes after their last unlink

Previously fusefs would never recycle vnodes.  After VOP_INACTIVE, they'd
linger around until unmount or the vnlru reclaimed them.  This commit
essentially actives and inlines the old reclaim_revoked sysctl, and fixes
some issues dealing with the attribute cache and multiply linked files.
