anv: Move close(fd) from anv_bo_cache_import to its callers (v2)

This will allow us to implement VK_ANDROID_native_buffer without dup'ing
the fd. We must close the fd in VK_KHR_external_memory_fd, but we should
not in VK_ANDROID_native_buffer.

v2:
  - Add missing close(fd) for case
    VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_OPAQUE_FD_BIT_KHR, subcase
    ANV_SEMAPHORE_TYPE_BO.
