This code use strlen(buf) to find the number of characters printed.
That's sort of ugly and unnecessary because we can just use the
return from scnprintf() instead.
Also since strlen() does not count the NUL terminator, that means
"QEDE_FW_VER_STR_SIZE - strlen(buf)" is never going to be zero so
that condition can be removed.
