You can modify <sup> a little so that it does not alter the paragraph
line spacing so much. In this example, with a value of 0em, it is
positioned on the baseline:
#+HTML_HEAD: <style> sup {vertical-align: baseline;position: relative;bottom:
0em;} </style>
Another slightly dirtier way is with an export filter in your document.
The sub tag is removed and the reference number is enclosed in square
brackets, separated by a space from the previous word:
#+BIND: org-export-filter-footnote-reference-functions (footnote-sup-filter)
#+begin_src emacs-lisp :exports results :results none
(defun footnote-sup-filter (text backend info)
(when (org-export-derived-backend-p backend 'html)
(replace-regexp-in-string "<a" " <a"
(replace-regexp-in-string "\\([[:digit:]]+\\)\\(</a\\)" "[\\1]\\2"
(replace-regexp-in-string "</?sup>" "" text)))))
#+end_src
