serial: qcom-geni: trace: Drop redundant len field from geni_serial_data

The dynamic array stored in the ring buffer already carries its own
length in the array metadata. There is no need to also store it as a
separate scalar field in the entry struct.

Drop __field(unsigned int, len) and the corresponding __entry->len
assignment, and use __get_dynamic_array_len(data) in the TP_printk for
both the len=%u format argument and the __print_hex() size argument.
This saves 4 bytes per event on the ring buffer.
