Fix dl2k constants

Fix dl2k constants

patch 9c52fab2f187636b39afb0dcf562872ed42ab608 in mainline.

The MSSR constants didn't match the reality - bitfield declarations
used to be correct (1000BT_FD - bit 11, 1000BT_HD - bit 10), but enum
had them the other way round.  Went unnoticed until the switch from
the bitfields use to the explicit arithmetics and I hadn't caught that one
when verifying correctness of change...
