kernel test robot reports kernel-doc warning:

>> fs/btrfs/zstd.c:98: warning: This comment starts with '/**', but
isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst

The warning is caused by missing function name (in this case
zstd_reclaim_timer_fn) in the comment.

Add the function name.

This is the wrong fix.  Static functions should not have kernel-doc
comments.  Just delete the second '*' at the head of the comment.

Also, btrfs developers should be testing with W=1.  That will catch
these problems before the code is integrated.

Oops, thanks for reminding me.
