FBSD CM: don't call afs_close when recycling
Don't call afs_close when handling VOP_CLOSE on a recycled
vnode, since there was no matching open. This corrects the
opens count, which was seen to go have gone negative in the
reclaim vop. For clarity, assert if afs_vop_close is entered
with a VI_DOOMED vnode and avc->opens != 0.
