[PATCH OBV] Remove dead code in regcache::dump

[PATCH OBV] Remove dead code in regcache::dump

[Yao Qi]

footnote_register_size in regcache::dump is a constant zero, so the
condition check against footnote_register_size is dead code.  The code
writing to footnote_register_size was removed by 01e1877.

This patche removes footnote_register_size and the dead code.
