cluster/afr: dir-write: Fix inode number handling.
create, mkdir, symlink, mknod: Prefer to return itransform'd inode number
from the first_up_child. If not, fall back on any other child that returned
succcess.
link, rename: Return the same inode number that
was passed as part of loc_t.
Also adds a new member to afr_local_t, local->first_up_child
which is initialized at the start of the transaction. This
fixes the race where a subvolume might go down during the transaction
and thus have the first_up_child change.
