New compiler warning

[Po Lu]

Compiling a build without SQlite has lately started to yield this
warning:

In end of data:
emacs-lisp/multisession.el: Warning: the function ‘sqlite-rollback’ is not 
known to be defined.

I don't see any call to that function in multisession.el, so my
hypothesis is it's being called by a macro which does not take
precautions for Emacs builds absent that function.  Would someone please
address this?
