InputNumber's onInputBlur fails when component gets destroyed

[cooliopas]

When using InputNumber inside a Dialog with closeOnEscape="true" or dismissableMask="true", onInputBlur gets executed when the component is already destroyed, so it throws an error.

It affects PrimeVUE 2 and PrimeVUE 3.

You can easily reproduce it on https://www.primefaces.org/primevue/showcase/#/datatable/crud:

• Click on "+NEW" button.
• Focus the "Quantity" InputNumber
• Press ESC key to close the Dialog
