AOSP version: android_14.0.0_r1
How to reproduce:
1.lunch sdk_phone_x86_64-userdebug
2.run in vts-tradefed "vts -m VtsHalNeuralnetworksTargetTest --gtest_filter=TestGenerated/MemoryDomainTest.Test/android_hardware_neuralnetworks_IDevice_nnapi_sample_all_conv_quant8"
3.logcat has message: "E android.hardware.neuralnetworks-service-sample-all: lockImpl:296 failed with 'Error3::BAD_VALUE'////Gralloc3: lock(0x7c65afedee00, ...) failed: 3"

Before android_14.0.0_r1, in cb_handle_30_t.lockedUsage is only for cb->hostHandle==true, but from android_14.0.0_r1, it seems to check all usage in mapper3.cpp

    Error3 lockImpl(void* raw,
                    const uint64_t uncheckedUsage,
                    const Rect& accessRegion,
                    const hidl_handle& acquireFence,
                    void** pptr,
                    int32_t* pBytesPerPixel,
                    int32_t* pBytesPerStride) {
        if (!raw) {
            RETURN_ERROR(Error3::BAD_BUFFER);
        }
        cb_handle_30_t* cb = cb_handle_30_t::from(raw);
        if (!cb) {
            RETURN_ERROR(Error3::BAD_BUFFER);
        }
        if (cb->lockedUsage) {
            RETURN_ERROR(Error3::BAD_VALUE);
        }

In IMapper.h, it has bellow comments:

1D buffers (width = size in bytes, height = 1, pixel_format = BLOB) must * "lock in place". The buffers must be directly accessible via mapping. 

So, before android_14.0.0_r1, we can lock buffer many times, and from android_14.0.0_r1, seems we can only lock buffer once. And I check the commit id: https://cs.android.com/android/_/android/device/generic/goldfish-opengl/+/855b99ace858ea66dd572e1d672a4c5419dc2225, but I cannot find the clue.

NNAPI VTS wrong usage? or mapper wrong? Looking forward to your reply, thanks.
