Wildcard expansion is performed by the shell; -r is handled by grep,
but only applies to whatever arguments are given to it by the shell.
In this case, the shell expands *.h to a list of all header files in
the current directory, and passes those to grep.  grep would recurse
on those, since -r was given, but none of them are directories.  This
will do what you want:
find . -name '*.h' | xargs grep "struct timeval" /dev/null
