ena_device_init() initializes the MMIO read mechanism with
ena_com_mmio_reg_read_request_init(), which allocates a coherent DMA
buffer for MMIO read responses.
The normal removal path releases this buffer through
ena_com_mmio_reg_read_request_destroy(). However, if ena_probe() fails
after ena_device_init() succeeds, the error path destroys the admin
resources and eventually frees ena_dev without destroying the MMIO read
request, leaving the coherent DMA buffer allocated.
Call ena_com_mmio_reg_read_request_destroy() in the probe error path
before releasing the remaining device resources.
This issue was found by manual code inspection.
