Fix race when looking up reclaimable inodes

If we get a race looking up a reclaimable inode, we can
end up with the winner proceeding to use the inode before
it has been completely re-initialised. This is a Bad Thing.

Fix the race by checking whether we are still initialising the
inod eonce we have a reference to it, and if so wait for the
initialisation to complete before continuing.

While there, fix a leaked reference count in the same code
when encountering an unlinked inode and we are not doing a
lookup for a create operation.
