net/smc: fix valid DMBE buffer sizes
[ Upstream commitef12ad4588
] 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. Fixes:c6ba7c9ba4
