perf/hw_breakpoint: Enable breakpoint in modify_user_hw_breakpoint Currently we enable the breakpoint back only if the breakpoint modification was successful. If it fails we can leave the breakpoint in disabled state with attr->disabled == 0. We can safely enable the breakpoint back for both the fail and success paths by checking the bp->attr.disabled, which either holds the new 'requested' disabled state or the original breakpoint state.
