Bug 109253 – [BlackBerry] webpage needs null check in BackingStore::setCurrentBackingStoreOwner

• Component: WebKit BlackBerry
• Status: RESOLVED FIXED

[Charles Wei]

In 
void BackingStorePrivate::setCurrentBackingStoreOwner(WebPage* webPage)
{
    // Let the previously active backingstore release its tile buffers so
    // the new one (e.g. another tab) can use the buffers to render contents.
    if (BackingStorePrivate::s_currentBackingStoreOwner && BackingStorePrivate::s_currentBackingStoreOwner != webPage)
        BackingStorePrivate::s_currentBackingStoreOwner->d->m_backingStore->d->resetTiles();

    BackingStorePrivate::s_currentBackingStoreOwner = webPage;
    webPage->backingStore()->d->updateSuspendScreenUpdateState(); // depends on isActive()
}

webPage could be null when a tab is been deleted, so we need to check for null before using webPage.
