tracing: Fix documentation on tp_printk cmdline option 



kernel-parameters.txt incorrectly states that workings of
kernel.tracepoint_printk sysctl depends on "tracepoint_printk kernel
cmdline option", this is a bit misleading for new users since the actual
cmdline option name is tp_printk.

Fixes: 0daa2302 ("tracing: Add tp_printk cmdline to have tracepoints go to printk()")
