Konstantin Belousov 427ef27ec7 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.
