net/smc: fix valid DMBE buffer sizes
[ Upstream commit ef12ad45880b696eb993d86c481ca891836ab593 ]
The SMCD_DMBE_SIZES should include all valid DMBE buffer sizes, so the
correct value is 6 which means 1MB. With 7 the registration of an ISM
buffer would always fail because of the invalid size requested.
Fix that and set the value to 6.
