Subject: surfaceflinger: fix current transform hint

BufferQueueLayer was missing updateTransformHint on first ref.
This resulted in VulkanPreTransformTest
testVulkanPreTransformSetToMatchCurrentTransform failure.

Bug: 112439036
Test: run cts -m CtsGraphicsTestCases \
            -t android.graphics.cts.VulkanPreTransformTest
