Changed pinMode() default interrupt type DISABLED to previously set (espressif#6695)

* Changed in pinMode() default  intr_type

pins default configuration has intr_type =  GPIO_INTR_DISABLE
With this implementation, it will set the intr_type to previously set intr_type. It will no longer disable interrupt, when pinmode is called multiple times on same pin with interrupt enabled.
