xtensa: fix KASAN report for show_stack

commit 1d3b7a788ca7435156809a6bd5b20c95b2370d45 upstream.

show_stack dumps raw stack contents which may trigger an unnecessary
KASAN report. Fix it by copying stack contents to a temporary buffer
with __memcpy and then printing that buffer instead of passing stack
pointer directly to the print_hex_dump.
