kernel: Init back pointer to microkernel task

Browse source 
Fibers initialize this back pointer to NULL as they are (by definition)
not microkernel tasks.  Microkernel tasks initialize it to their
corresponding 'ktask_t'.

However for nanokernel systems, the back pointer is always NULL. This
is because there is only one task in a nanokernel system (the background
task) and it can not pend on a nanokernel object--it must poll.
