[PATCH 14/19] Remove usage of find_inferior in linux_resume

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

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

Replace with for_each_thread.

gdb/gdbserver/ChangeLog:

	* linux-low.c (linux_resume_one_thread): Return void, take
	parameter directly.
	(linux_resume): Use for_each_thread.
