[PATCH 2/4] MIPS: traps: Fix output of show_stacktrace

[Matt Redfearn <matt.redfearn@imgtec.com>]

Since commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing
continuation lines") the output from show_stacktrace on MIPS has been
pretty unreadable due to the lack of KERN_CONT markers. Use pr_cont to
provide the appropriate markers & restore the expected output. Also
start a new line with printk such that the presence of timing
information does not interfere with output.
