Revert "drivers/tty: Explicitly pass current to show_stack"
This reverts commit 9f12cea96f47f98d612a0a0b84f950a0163731bf. Mark writes: Unfortunately, this patch will result in erroneous stack traces on some architectures. Sorry about this; I should have verified this more thoroughly before sending the series out. Please drop the patch at your earliest convenience.
