ANDROID: fix up struct task_struct ABI change in 5.10.162

In commit 788d0824 ("io_uring: import 5.15-stable io_uring"), a new
field was added to struct task_struct.  Move it to the proper location
and macro in order to preserve the kernel ABI.

The .xml file is updated to reflect this abi change:

type 'struct task_struct' changed
  member 'union { void* pf_io_worker; struct { u64 android_kabi_reserved1; }; union { }; }' was added
  member 'u64 android_kabi_reserved1' was removed
