WMaker: change conceptually imperfect code in drawerDestroy (Coverity #50265)

Browse Source 
Factually, the program works because the function 'drawerRemoveFromChain'
uses only the address of the drawer and not the content of the structure,
but conceptually this address point to a storage space that has been
de-allocated, so that's calling for trouble for future code changes.
