kernel/amd64: Do not run off callstack in trace
Previously, if RBP becomes NULL (indicating that the END of the
callstack has been reached), we still had a chance of dereferencing a
NULL pointer when attempting to grab the next value for 'rip'. This
commit checks if RBP is NULL before we get the next instruction pointer
value.
