[PATCH] INIT_TASK/INIT_TSS cleanup

Ingo added saved_fs, saved_gs to thread_struct and didn't add
corresponding initializers to INIT_THREAD.  We assign NULL to an
unsigned int and the compiler warns.

The patch converts it to use designated initialisers and fixes the
io_bitmap initializer in the process.
