Subject: [PATCH] kernel: tracing: use modern function declaration

We get a lot of harmless warnings about this header file at W=1 level
because of an unusual function declaration:

kernel/trace/trace.h:766:1: error: 'inline' is not at beginning of declaration [-Werror=old-style-declaration]

This moves the inline statement where it normally belongs, avoiding the
warning.

Fixes: 4046bf023b06 ("ftrace: Expose ftrace_hash_empty and ftrace_lookup_ip")
