Subject: [PATCH 6/7] perf tools: Fix bug when --raw-dump is not the first arguement for perf list.

As we use PARSE_OPT_STOP_AT_NON_OPTION option in parse_option(), if --raw-dump
is not the first argument, it will be treat as an argument rather than option.

Example:
	# ./perf list kvmmmu --raw-dump
	  kvmmmu:kvm_mmu_pagetable_walk                      [Tracepoint event]
	  kvmmmu:kvm_mmu_paging_element                      [Tracepoint event]
	  kvmmmu:kvm_mmu_set_accessed_bit                    [Tracepoint event]
	  kvmmmu:kvm_mmu_set_dirty_bit                       [Tracepoint event]
	  kvmmmu:kvm_mmu_walker_error                        [Tracepoint event]
	  kvmmmu:kvm_mmu_get_page                            [Tracepoint event]
	  kvmmmu:kvm_mmu_sync_page                           [Tracepoint event]
	  kvmmmu:kvm_mmu_unsync_page                         [Tracepoint event]
	  kvmmmu:kvm_mmu_prepare_zap_page                    [Tracepoint event]
	  kvmmmu:mark_mmio_spte                              [Tracepoint event]
	  kvmmmu:handle_mmio_page_fault                      [Tracepoint event]
	  kvmmmu:fast_page_fault                             [Tracepoint event]

This patch replace PARSE_OPT_STOP_AT_NON_OPTION with 0, then we can parse it even if
it is not the first argument.

Verification:
	# ./perf list kvmmmu --raw-dump
	kvmmmu:kvm_mmu_pagetable_walk kvmmmu:kvm_mmu_paging_element
	 kvmmmu:kvm_mmu_set_accessed_bit kvmmmu:kvm_mmu_set_dirty_b
	it kvmmmu:kvm_mmu_walker_error kvmmmu:kv
