xtensa: fix get_wchan
commit d90b88fd3653f1fb66ecc6571b860d5a5749fa56 upstream.
Stack unwinding is implemented incorrectly in xtensa get_wchan: instead
of extracting a0 and a1 registers from the spill location under the
stack pointer it extracts a word pointed to by the stack pointer and
subtracts 4 or 3 from it.
