[PATCH 21/31] udp.c: Remove some (ab)use of variable name `i'

[Ian Jackson]

I find it very odd to find `item_t *i' etc.  I would like to be able
to use `int i'.  So change some uses of `i' to `item'.  (`j' in this
function will go away in the next patch so isn't worth renaming.)

No functional change.
