patches: fix two compile errors (stray unbind_to, voiceoverSetPoint scope)

Two bugs introduced during rebase/amend:

1. Stray 'unbind_to (count, Qnil)' in ns_focus (P0000):
   A hunk was misplaced into ns_focus where 'count' is not declared.
   The comment and unbind_to belonged at the end of ns_zoom_track_completion,
   which already has a correct unbind_to.  Remove the duplicate from ns_focus.

2. 'voiceoverSetPoint = NO' in EmacsView::initFrameFromEmacs: (P0008):
   voiceoverSetPoint is a BOOL ivar of EmacsAXBuffer, not EmacsView.
   Setting it in EmacsView's init method causes 'undeclared identifier'.
   ObjC BOOL ivars zero-initialize to NO automatically.  Remove the line.
   voiceoverSetPoint is consumed/set in EmacsAXBuffer methods only.
