[PATCH] i40e: avoid use of uninitialized v_budget in i40e_init_msix

["John W. Linville" <linville@tuxdriver.com>]

This I40E_FCOE block increments v_budget before it has been initialized,
then v_budget gets overwritten a few lines later.  This patch just
reorders the code hunks in what I believe was the intended sequence.
