Subject: staging: ccree: fix 64 bit scatter/gather DMA ops

From: Gilad Ben-Yossef <gilad@benyossef.com>

commit e0b3f39092a1cff5548cbaf40096ec25e7721de6 upstream.

Fix a wrong offset used in splitting a 64 DMA address to MSB/LSB
parts needed for scatter/gather HW descriptors causing operations
relying on them to fail on 64 bit platforms.
