stacktrace: don't crash on invalid stack trace structs
This patch makes the stacktrace printout code \warn when the entries pointer is unset rather than crashing when trying to access it in an attempt to make it a bit more robust. I was saving a stacktrace into an skb and forgot to copy it across skb copies... I have since fixed the code, but it would have been easier had the kernel not crashed in an interrupt.
