qlge allocates chunks from a page that it maps and unmaps that page when
the last chunk is released. When the driver is unloaded or the card is
removed, all chunks are released and the page is unmapped for the last
chunk.

However, when the last chunk of a page is not allocated and the device
is removed, that page is not unmapped. In fact, its last reference is
not put and there's also a page leak. This bug prevents a device from
being properly hotplugged.

When the DMA API debug option is enabled, the following messages show
the pending DMA allocation after we remove the driver.

This patch fixes the bug by unmapping and putting the page from the ring
if its last chunk has not been allocated.

pci 0005:98:00.0: DMA-API: device driver has pending DMA allocations while released from device [count=1]
One of leaked entries details: [device address=0x0000000060a80000] [size=65536 bytes] [mapped with DMA_FROM_DEVICE] [mapped as page]
