sched/assert.c: Print process name in assert dump

Browse Source 
In addition to printing out the thread name (task name in flat mode),
print the parent process's name as well.

It is quite useful to know which process is the parent of a faulting
thread, although this information can be read from the assert dump, in
some cases the dump might be incomplete (due to e.g. stack corruption,
which causes another exception and PANIC().)
