Prevent warnings on attributes handled by base class

SdXMLNumberFormatImportContext iterated the attribute list a second time
after its SvXMLNumFormatContext base had already consumed it, emitting
XMLOFF_WARN_UNKNOWN for everything except number:automatic-order.

This prevents warnings like:

    warn:xmloff:...:XMLNumberStyles.cxx:595: unknown attribute urn:oasis:names:tc:opendocument:xmlns:style:1.0 style:name value=D6

for attributes the base class already handles correctly.
