[PATCH 08/19] Remove usage of find_inferior in linux_mourn

[Simon Marchi <simon dot marchi at ericsson dot com>]

From: Simon Marchi <simon.marchi@polymtl.ca>

Replace with for_each_thread with pid filtering.  The callback becomes
trivial enough that it's better to inline it.

gdb/gdbserver/ChangeLog:

	* linux-low.c (delete_lwp_callback): Remove.
	(linux_mourn): Use for_each_thread.
