[PATCH 10/11] Remove usages of find_thread when calling need_step_over_p

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

Replace with find_thread.

gdb/gdbserver/ChangeLog:

	* linux-low.c (need_step_over_p): Return bool, remove dummy
	argument.
	(linux_resume, proceed_all_lwps): Use find_thread.
