scsi: qla2xxx: Fix DMA unmap leak
[ Upstream commit 5d328de64d89400dcf9911125844d8adc0db697f ]
With debug kernel we see following wanings indicating memory leak.
[28809.523959] WARNING: CPU: 3 PID: 6790 at lib/dma-debug.c:978
dma_debug_device_change+0x166/0x1d0
[28809.523964] pci 0000:0c:00.6: DMA-API: device driver has pending DMA
allocations while released from device [count=5]
[28809.523964] One of leaked entries details: [device
address=0x00000002aefe4000] [size=8208 bytes] [mapped with DMA_BIDIRECTIONAL]
[mapped as coherent]
Fix this by unmapping DMA memory.
