SVN rev 209367 on 2010-06-20 13:35:16Z by kib
Ensure that VOP_ACCESSX is called with exclusively locked vnode for
the kernel compiled with QUOTA option. ufs_accessx() upgrades the vdp
vnode lock from shared to exclusive to assign the dquot structure to
the vnode, and ufs_delete_denied() is called when tvp is locked. Since
upgrade drops shared lock when non-blocked upgrade failed, LOR is there.
