Viktor Rosendahl 85a1da3d7a tools/latency-collector: Use correct size when writing queue_full_warning
[ Upstream commit f604de20c0 ]

queue_full_warning is a pointer, so it is wrong to use sizeof to calculate
the number of characters of the string it points to. The effect is that we
only print out the first few characters of the warning string.

The correct way is to use strlen(). We don't need to add 1 to the strlen()
because we don't want to write the terminating null character to stdout.
