If first call of the procedure is failed on
the open_table stage stmt_arena->state is set to
EXECUTED state. On second call(if no errors on
open_table stage) it leads to use of worng memory arena
in find_field_in_view() function as
thd->stmt_arena->is_stmt_prepare_or_first_sp_execute()
returns FALSE for EXECUTED state. The item is created 
not in its own arena and it leads to crash on further
calls of the procedure.
The fix: 
change state of arena only if
no errors on open_table stage happens.
