Konstantin Belousov 8db679af66 UFS: make mkdir() and link() reliable when using SU and reaching nlink limit ... i_nlink overflow might be transient, i_effnlink indicates the final value of the link count after all dependencies would be resolved. So if i_nlink reached the maximum but i_efflink did not, we should be able to make the link by syncing. We must sync the whole filesystem to resolve dependencies, which requires unlocking vnodes locked for VOPs. Use existing ERELOOKUP/VOP_UNLOCK_PAIR() mechanism to restart the VOP if sync with unlock was done.
