[Intel-wired-lan] [next PATCH S34 07/12] i40e: Fix uninitialized variable

[Harshitha Ramamurthy]

From: Catherine Sullivan <catherine.sullivan at intel.com>

We have an uninitialized variable warning for valid_len for one case in
validate_vf_mesg. To fix this, just initialize it to 0 at the top of the
function and remove all of the now redundant assignments to 0 in the
individual cases.
