[PATCH 2/3] Remove dead code for dprintf.

[Yao Qi <yao at codesourcery dot com>]

Hi,
For a given dprintf B, B->commands can never be null, so the condition
below is always false.  This patch is to remove it as sort of dead
code.

When creating a dprintf B, the following call chain can be found
unconditionally,

init_breakpoint_sal
  --> update_dprintf_command_list (because B->extra_string can't be null)
         --> breakpoint_set_commands (because PRINT_LINE can't be null)
                --> set B->commands.
gdb:

	* breakpoint.c (print_one_breakpoint_location): Remove dead code.
