[PATCH 06/11] Remove usage of find_inferior in unsuspend_all_lwps

[Simon Marchi <simon.marchi@ericsson.com>]

Replace with for_each_thread.  I inlined unsuspend_one_lwp in
unsuspend_all_lwps, since it is very simple.

gdb/gdbserver/ChangeLog:

	* linux-low.c (unsuspend_one_lwp): Remove.
	(unsuspend_all_lwps): Use for_each_thread, inline code from
	unsuspend_one_lwp.
