assert: show stacks with the sp from regs

1. Get the value of sp from dump regs when an exception occurs,
   to avoid getting the value of fp from up_getsp and causing
   incomplete stack printing.
2. Determine which stack the value belongs to based on the value
   of SP to avoid false reports of stack overflow
