Subject: camera 3_4: Fix compilation errors

Compile Error:
hardware/libhardware/modules/camera/3_4/camera.cpp:502:9: error: non-constant-expression cannot be narrowed from type 'std::__1::vector<camera3_stream_buffer, std::__1::allocator<camera3_stream_buffer> >::size_type' (aka 'unsigned long') to 'uint32_t' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]
        request->output_buffers.size(),
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Compile Error:
hardware/libhardware/modules/camera/3_4/v4l2_gralloc.cpp:168:15: error: use of undeclared identifier 'EINVAL'
      return -EINVAL;

Test: Add to device.mk
        USE_CAMERA_V4L2_HAL := true
        PRODUCT_PACKAGES += camera.v4l2
