scsi: qla2xxx: Fix DMA unmap leak
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.
