[ Upstream commit 7f0b8a56c978b0a3315ac84c6cbb065413afb8e9 ]

Commit 6559a7e8296002b4 ("cxgb4: Cleanup macros so they follow the same style and look consistent") introduced a regression where reading MC1 memory in adapters where MC0 isn't present or MC0 size is not equal to MC1 size caused the adapter to crash due to incorrect computation of memoffset. Fix is to read the size of MC0 instead of MC1 for offset calculation
