IB/mthca: Fix allocation of ICM chunks in coherent memory
The change to allow allocating ICM chunks from coherent memory did not
increment the count of sg entries properly, so a chunk that required
more than allocation would not be mapped properly by the HCA.
Fix this by adding the missing increment of chunk->nsg.
