[RFA/mips] Remove mips16 code that seems redundant

Thanks! I have committed this change:

2004-10-10  Joel Brobecker  <brobecker@gnat.com>

        * mips-tdep.c (mips16_scan_prologue): Remove redundant code.

(just to note the slight change in the function name, since a rename
was made since then - patch is identical so not reproduced here).
