[Xen-devel] [PATCH v2 1/1] tools/livepatch: cleanup unnecessary "j = ARRAY_SIZE(action_options); "

[Dongli Zhang <dongli.zhang@xxxxxxxxxx>]

Local variable "j" would be used only when "i == ARRAY_SIZE(main_options)"
is true. Thus, it is not necessary to update "j" when "i ==
ARRAY_SIZE(main_options)" is false.
