Subject: [PATCH] remove unused pid_max in trace.h

euler inclusion
category: bugfix
bugzilla: 14007
CVE: NA

-------------------------------------------------

In commit b8f8307ae1e9 ("pid_ns: Make pid_max per namespace"), pid_max
is made per namespace, so global pid_max in trace.h is unused now.
Remove it.
