Fixed bug #28244.

Browse Source 
When the same VIEW was created at the master side twice,
malformed (truncated after the word 'AS') query string 
was forwarded to client side, so error messages on the
master and client was different, and replication was
broken.

The mysql_register_view function call failed
too early: fields of `view' output argument of this 
function was not filled yet with correct data required
for query replication.
The mysql_register_view function also copied pointers to 
local buffers into a memory allocated by the caller.


sql/sql_view.cc:
  Fixed bug #28244.
  Checking of existence of VIEW .frm file has been
  moved down to the place, when `view' argument is
  completely filled with proper data.
  view->query.str and view->query.md5 pointers has been
  set to the NULL before return from the mysql_register_view
  function.
