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).

Closing this since the mentioned improvement is in repository. Didn't check since when.
