[PATCH] arch/x86/kernel/tsc_sync.c: Clean up code by removing unused assignment

[mateusznosek0@gmail.com]

From: Mateusz Nosek <mateusznosek0@gmail.com>

Previously the assignment to local variable 'now' took place before the for
loop. The loop is unconditional so it will be entered at least once. The
variable 'now' is reassigned in the loop and is not used before reassigning.
Therefore the assignment before the loop is unnecessary and can be removed.
