Subject: [PATCH] quiet down swiotlb warnings

It turns out that the qla2xxx driver sometimes fills up the iotlb
on purpose and throttles itself when pci_map_sg() fails.  In the
case of a driver that expects and handles pci_map_sg() failures,
we should not spam the user's console with swiotlb full messages.

If the user runs a driver that cannot handle the swiotlb filling
up, 5 warnings should be enough to leave a clue.
