Fix use of uninitialized variables to stop auto-unassigning racks:

0x7ee948
8B 7C 24 3C
89 C7 90 90

.text:08836948                 mov     edi, eax
.text:0883694A                 nop
.text:0883694B                 nop


0x7eea2f
8B 7C 24 3C
89 C7 90 90

.text:08836A2F                 mov     edi, eax
.text:08836A31                 nop
.text:08836A32                 nop


basically:

  b_squad_id = building->getSpecificSquad();
- if (b_squad_id != squad->id || !building->canUse(some_squad_id, 4))
+ if (b_squad_id != squad->id || !building->canUse(b_squad_id, 4))
    unassign(building);

the reason being, some_other_squad_id contains irrelevant garbage at this point
