CLEANUP: stick-tables: Don't needlessly compute shard number in stksess_free()

Since commit 0bda33a3e ("MINOR: stick-tables: remove the uneeded read lock
in stksess_free()"), the lock on the shard is no longer acquired. So it is
useless to still compture the shard number. The result is never used and can
be safely removed.
