If the caps.eqe_size is bigger than the struct mlx4_eqe then there
is a potential for corrupting data at the master context. We can see
the message "Master failed to generate an EQE for slave: X" when the
event_eqe array wraps and we can see potential oops at the function
mlx4_GEN_EQE. Also correct a memset of cmd_eqe to use the sizeof
mlx4_eqe instead of eqe_size.

Thanks Carol, I'd like to review this a bit more tomorrow and will
send it with another fix/es to net

Sure thanks.
