audit: Fix possible return value truncation in audit_get_context()

The audit subsystem treats syscall return codes as type long, unfortunately the audit_get_context() function mistakenly converts the return code to an int type in the parameters which could cause problems on systems where the sizeof(int) != sizeof(long).

Applied. E.g. for mmap() it's actually easy to trigger on 64bit boxen.
