Some of the frames marked as GSO which arrive at
virtio_net_hdr_from_skb() have no GSO_TYPE, no
fragments (data_len = 0) and length significantly shorter
than the MTU (752 in my experiments).
This is observed on raw sockets reading off vEth interfaces
in all 4.x and 5.x

Implement a generic function for removing reserved regions. This can be
used by drivers that don't do anything fancy with these regions other
than allocating memory for them.

Most IOMMU drivers only need to free the memory allocated for each
reserved region. Instead of open-coding the loop to do this in each
driver, extract the code into a common function that can be used by
all these drivers.

- change subject prefix to "iommu:

A bunch of drivers want to know which tx queue triggered a timeout,
and virtio wants to do the same.
We actually have the info to hand, let's just pass it on to drivers.
Note: tested with an experimental virtio patch by Julio.
That patch itself isn't ready yet though, so not included.
