Subject: MDEV-19351 statistics_for_command_is_needed: Conditional jump or move
            depends on uninitialised value

Initialized THD::force_read_stats introduced in the patch for MDEV-17605.
Leaving this field uninitialized in the constructor of the THD class may
trigger reading statistical data that is not needed.
