Ing. Jaroslav Šafka 3d89c8ba74 rmt: Fix LoadProhibited on RX END ...

Fixes exceptions LoadProhibited, when rmt tries read variable p_rmt on RX END which can be 0.
It happens after esp_reset()  (OTA) and the rmt is not probably stopped by it.
In other words the routine rmt_driver_isr_default was called before second rx channel was registered.

scenario:
register tx channel
register rx channel
reboot
register tx channel
-> exception (because rx channel is accessed)
