zap: reuse zap_leaf_t on dbuf reuse after shrink
If a shrink or truncate had recently freed a portion of the ZAP, the
dbuf could still be sitting on the dbuf cache waiting for eviction. If
it is then allocated for a new leaf before it can be evicted, the
zap_leaf_t is still attached as userdata, tripping the VERIFY.

Instead, just check for the userdata, and if we find it, reuse it.
