Fix ASAN error due to invalid type
ei_array is supposed to be an array of expert_entry items. However, it
was initialized of an array of expert_info_t items which is much larger.
This caused an ASAN error when running `tshark -z expert` because
expert_stat_packet wants to read past the stack.
Fix this by correcting the type. While at it, reduce the size of
expert_entry for 64-bit systems (reduces initial memory usage by 8
kilobytes) and avoid a redundant g_array_index call.
