omero.HdfStorage.update: add size check on data.rowNumbers

Currently if the omero.grid.Data passed to table.update() has
rowNumbers values outside the range of rows, the implementation will
raise an IndexError which will be returned as an InternalException
to the client.
This commit adds an initial call to self.__sizecheck(None, data.rowNumbers)
which should raise an ApiUsageException with an appropriate error
message in that scenario.
