Added missing initialization for va.va_dentry in zfs_get_xattrdir.

Browse Source 
Without this we may mistakenly believe we have a dentry and try to
d_instantiate() it.  This will result in the following BUG.  It's
important to note that while the xattr directory has an inode
assoicated with it we never create a dentry for it.

  kernel BUG at fs/dcache.c:1418!
