IB/mlx4: Convert is_xxx variables in build_mlx_header() to bool
Matches the way they're used, and actually lets at least x86-64 generate better code: add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-38 (-38) function old new delta mlx4_ib_post_send 4416 4378 -38 Signed-off-by: Roland Dreier <roland@purestorage.com>
