Revert "fuse: fix matching of FUSE_DEV_IOC_CLONE command"

This reverts commit 6076f5f341.

This is currently breaking avd/avd_boot_test_kernel_triggered on
kernel_virt_x86_64, when tested against android-mainline which is
preventing an up-level to v5.13-rc1.  We can do some more
investigation later, but for now, we'll simply revert the change.
