PatR 54cfb86936 fix pull request #340 - untrap steed sanity ...

When a failed #untrap attempt while mounted caused hero to be moved
onto the trap, it neglected to set the steed's coordinates to match.
If 'sanity_check' was On, that would trigger warnings about steed's
anomalous position.  Eventually a normal move would put steed's
coordinates back in sync with the hero's.

The pull request code set u.usteed->{mx,my} directly.  I've used
u_on_newpos() instead.  I also replaced some direct manipulations of
u.{ux,uy} with u_on_newpos() so that if clipping is in effect it will
be updated.

Fixes #340
