vrend: Fix wrong numlayers in vrend_make_view

The old code is buggy and set numlayers to 1 for GL_TEXTURE_2D_ARRAY
when creating the view. Just change to use array_size directly.

This fixes such tests in CtsNativeHardwareTestCases:

android.hardware.nativehardware.cts.AHardwareBufferNativeTests#MultipleLayers_ColorTest_MipmapComplete_GL_RGB8
android.hardware.nativehardware.cts.AHardwareBufferNativeTests#MultipleLayers_ColorTest_MipmapComplete_GL_RGBA16F
android.hardware.nativehardware.cts.AHardwareBufferNativeTests#MultipleLayers_ColorTest_MipmapComplete_GL_RGBA8
android.hardware.nativehardware.cts.AHardwareBufferNativeTests#MultipleLayers_ColorTest_MipmapComplete_GL_SRGB8_ALPHA8_sRGB
