fix(uart): re-initialize uart_event fields to some certain values for every loop

Browse Source 
Although uart_event.size and uart_event.timeout_flags fields are
meaningless to events other than UART_DATA, fix the values to 0 could
help reduce confusion.

Closes https://github.com/espressif/esp-idf/issues/12299
