It is up to the caller to convert the fork format to extent format before calling into xfs_bmapi_write() so format conversion can be done correctly. The code in xfs_bmapi_write() to convert the format is used implicitly by the attribute and directory code, but they specifically zero the fork size so that the conversion does not do any allocation or manipulation. Move this conversion into the shortform to leaf functions for the dir/attr code so the conversions are explicitly controlled by all callers. Now we can remove the conversion code in xfs_bmapi_write.
