We won't normally have a ton of flow masks but using a size_t to store
values no bigger than sizeof(struct sw_flow_key) seems excessive.
This reduces sw_flow_key_range and sw_flow_mask by 4 bytes on 32-bit
systems. On 64-bit systems it shrinks sw_flow_key_range by 12 bytes but
sw_flow_mask only by 8 bytes due to padding.
Compile tested only.
