Will Deacon 60916a9382 tracing/syscalls: Fix perf syscall tracing when syscall_nr == -1 
syscall_get_nr can return -1 in the case that the task is not executing
a system call.

This patch fixes perf_syscall_{enter,exit} to check that the syscall
number is valid before using it as an index into a bitmap.
