Marc Mutz 239b71d07d Fix use-after-delete bug in tst_QWidget::taskQTBUG_27643_enterEvents() 
ASAN report:

  READ of size 8 at 0x606000011990 thread T0
    #0 0x505e3b in EnterTestMainDialog::eventFilter(QObject*, QEvent*) tests/auto/widgets/kernel/qwidget/tst_qwidget.cpp:10294
    [...]

  0x606000011990 is located 48 bytes inside of 56-byte region [0x606000011960,0x606000011998)
  freed by thread T0 here:
    #0 0x2b8df3551c79 in operator delete(void*) ../../../../gcc/libsanitizer/asan/asan_new_delete.cc:92
    #1 0x418ab5 in EnterTestMainDialog::buttonPressed() tests/auto/widgets/kernel/qwidget/tst_qwidget.cpp:10276

  previously allocated by thread T0 here:
    #0 0x2b8df3551739 in operator new(unsigned long) ../../../../gcc/libsanitizer/asan/asan_new_delete.cc:60
    #1 0x4188cf in EnterTestMainDialog::buttonPressed() tests/auto/widgets/kernel/qwidget/tst_qwidget.cpp:10272

EnterTestMainDialog::eventFilter() checks for nullness of 'modal'
before accessing it, but buttonPressed() did not reset 'modal'
to nullptr after deletion.
