Three minor updates from the code review of https://github.com/open-mpi/ompi-release/pull/933: * Remove an extra blank line a show_help message * We no longer allow -1 for the MCA param btl_usnic_av_eq_num, so change the flag to REGINT_GE_ONE * Change "num_blocks" definition to be in terms of block_len (not eq_size)
