Seems some compilers complain on the volatility of thread_holding not being loaded in an ink_assert.

{code}
In file included from ./I_Continuation.h:40:
./I_Lock.h:350:15: error: expression result unused; assign into a variable to force a volatile load [-Werror,-Wunused-volatile-lvalue]
    (void)(m->thread_holding);
           ~  ^~~~~~~~~~~~~~
./I_Lock.h:383:15: error: expression result unused; assign into a variable to force a volatile load [-Werror,-Wunused-volatile-lvalue]
    (void)(m->thread_holding);
           ~  ^~~~~~~~~~~~~~
