Cap 64bit userspace backtraces to PERF_MAX_STACK_DEPTH
We cap 32bit userspace backtraces to PERF_MAX_STACK_DEPTH
(currently 127), but we forgot to do the same for 64bit backtraces.
If userspace creates a stack frame that points to itself we will
loop forever in the backtrace code with interrupts off.
