rlink: Fix DTC command timeout

With the current timeout setting i = 10 in drtc_run_timeout()
I get "Error: too many retries waiting for DTC status" when
loading a program into the FLASH of an STM32F1.

By experimentation a value of i = 22 was found to be the minimum
on my system. Therefore the value has been increased to i = 50.
