Given that _IO('T', 0x1) is _IOC(_IOC_NONE, 'T', 0x1, 0),
something like _IOC(_IOC_NONE, 'T', 0x1, 0x1) should be OK.

So remove the pidfd == 0 check. Userspace that needs to be portable
to kernels without CLONE_PIDFD support is advised to initialize pidfd
with -1 and check the pidfd value returned by CLONE_PIDFD.
