TAKE - switch to ilookup

[hch@xxxxxxxxxxxxxxxxxxxxx]

Switch from iget_locked to ilookup in vn_get.  We only want to
get the inode if it actually is present in core.  The new ilookup
function allows us to do this easily instead of having to tear down
the wrongly allocated inode again if it wasn't in memory.
