init_xfs_fs() calls dmapi_init() which does MOD_INC_USE_COUNT. Compile
XFS without DMAPI support and your problem will disappear.
The module related code in dmapi is a hangover from a time when dmapi
was a module in its own right instead of being linked into xfs.o. I
will remove module related code from dmapi, I will also review grio, to
make sure it does not have the same problem.
