Brian Behlendorf 53c7411919 Revert "Fix unlink/xattr deadlock" 
This reverts commit b00131d43c which
is no longer needed due to e89260a1c8.

This change forces all xattr znodes to hold a reference on their
parent which ensures prune_icache() will never attempt to evict
both the parent and child concurrently.  This effectively prevents
the deadlock condition from ever occuring.

Therefore we can safely revert back to the upstream synchronous
cleanup code.  This is nice because it keeps our code base closer
to upstream and resolves the performance issues introduced by the
original deadlock fix.
