[PATCH] drm/amd/display: remove redundant assignment to variable v_total

From: Colin Ian King <colin.king at canonical.com>

The variable v_total is being initialized with a value that is never
read and it is being updated later with a new value.  The initialization
is redundant and can be removed.

Addresses-Coverity: ("Unused value")
