[IB] mthca: Round up number of slots in HCA context memory table
When allocating a table for mem-free HCA context, don't assume that
obj_size * nobj is an even multiple of MTHCA_TABLE_CHUNK_SIZE. In
particular, make sure we allocate at least one slot even if the table
is smaller than MTHCA_TABLE_CHUNK_SIZE.
