    ixl: Report PF initialization failures to iflib
    
    ixl_if_init() returned early after AdminQ reconstruction, LAA, or
    VSI initialization failures.  Since IFDI_INIT has no return value,
    iflib then marked the interface RUNNING and enabled its interrupts
    and timers despite the incomplete hardware state.
    
    Use iflib_init_failed() on each incomplete path.  Also stop at the
    first ring-enable error and tear down any partially enabled rings
    before reporting failure.  This keeps the interface stopped and
    makes a later initialization attempt start from a bounded state.
    
    MFC after:      2 weeks
