Zhen Lei 3ab955de92 rcu: Align the output of RCU CPU stall warning messages
Time stamps are added to the output in kernels built with
CONFIG_PRINTK_TIME=y, which causes misaligned output.  Therefore,
replace pr_cont() with pr_err(), which fixes alignment and gets
rid of a couple of despised pr_cont() calls.

Before:

[   37.568668] CPU: 0 PID: 313 Comm: test0 Not tainted 6.1.0-rc4 #8

After:
