    libtcplay,cryptdisks: Fix GCC 12's -Wmaybe-uninitialized false positive
    
    This reverts commit b77d373551e67a9ce62d8063b8dd7bafd6f9e360 and
    correctly fix/silence the GCC 12's -Wmaybe-uninitialized warning, which
    is actually a false positive.
    
    GCC's rationale is: the memory 'mem' refers to was not initialized and
    may be used in mlock(). The 'mem' parameter is passed as 'const void *',
    so mlock() is impossible to initialize the memory.
