Steven Rostedt (VMware) e56b7b3b92 ftrace: Check for empty hash and comment the race with registering probes
commit 372e0d01da upstream.

The race between adding a function probe and reading the probes that exist
is very subtle. It needs a comment. Also, the issue can also happen if the
probe has has the EMPTY_HASH as its func_hash.
