comctl32: fixed some incorrect memory frees in status.c

[Gunnar Dalsnes]

comctl32->status.c->STATUSBAR_SetTextT:
-ntext wasn't freed on return if text was unicode
-part->text was allways freed, but if the previous style was 
SBT_OWNERDRAW, part->text would contain 32bit data (not a buffer ptr.)
-------------- next part --------------
