[Alan Hayward <Alan.Hayward@arm.com>]

The following commit broke the build for Arm:
d3a70e03cf51c8fb6bc183eaff7559edffec2045
Change iterate_over_lwps to take a gdb::function_view

Correct the changes made to arm_linux_insert_hw_breakpoint1 and make
similar changes to arm_linux_remove_hw_breakpoint1.

2019-03-18  Alan Hayward  <alan.hayward@arm.com>

	* arm-linux-nat.c (arm_linux_insert_hw_breakpoint1): Fix
	variable names.
	(arm_linux_remove_hw_breakpoint1): Use a gdb::function_view.
