Revert "proc/base: make prompt shell start from new line after executing "cat /proc/$pid/wchan""
This reverts the 4.6-rc1 commit 7e2bc81da333 ("proc/base: make prompt
shell start from new line after executing "cat /proc/$pid/wchan")
because it breaks /proc/$PID/whcan formatting in ps and top.
Revert also because the patch is inconsistent - it adds a newline at the
end of only the '0' wchan, and does not add a newline when
/proc/$PID/wchan contains a symbol name.
eg.
$ ps -eo pid,stat,wchan,comm
PID STAT WCHAN COMMAND
