Slight improvement in handling upper-boundary for DMA routines.

Attached is a small patch that moves the "line_count" upper limit calculation
outside the while loop in NVAccelUploadM2MF and NVAccelDownloadM2MF. Benefits
are (marginally) faster loops (less instructions, less branch-misses) and
slightly cleaner code (imho).
