MINOR: stktable: Save 8 bytes in stksess structure

Browse Source 
Thanks to the previous change, it is possible to save 8 bytes in the stksess
structure. the <shard> field is now a 16-bits unsigned integer. It is
possible because its max value is tested during parsing. <seen> is now a
8-bits integer because its value is 0 or 1. And <updt_type> is now 8-bits
integer too. It is one of STKSESS_UPDT_ value.
