[PATCH 1/1] Fix Compilation Warning in kernel/trace/trace.c

[Devendra Naga <devendra.aaru@gmail.com>]

there was a compilation warning saying
kernel/trace/trace.c:3644:8: warning: ‘page2’ may be used uninitialized in this function

The page2 pointer is used only when nr_pages = 2.

Assigned a null value to the page2 to get rid of warning.
