um: Always dump trace for specified task in show_stack
Currently, show_stack() always dumps the trace of the current task.
However, it should dump the trace of the specified task if one is
provided. Otherwise, things like running "echo t > sysrq-trigger"
won't work as expected.
Fixes: 970e51feaddb ("um: Add support for CONFIG_STACKTRACE")
