We were taking dcache_lock inside of i_lock, which introduces a dependency
not found elsewhere in the kernel, complicationg the vfs locking
scalability work. Since we don't actually need it here anyway, remove
it.
We only need i_lock to test for the I_COMPLETE flag, so be careful to do
so without dcache_lock held.
