ixgbe: dcb: BIT_APP_UPCHG not set by ixgbe_copy_dcb_cfg()
After this commit:
commit aacc1bea190d731755a65cb8ec31dd756f4e263e
Author: Multanen, Eric W <eric.w.multanen@intel.com>

ixgbe: driver fix for link flap
The BIT_APP_UPCHG bit is no longer set when ixgbe_dcbnl_set_all() is
called. This results in the FCoE app user priority never getting set
and the driver will not configure the tx_rings correctly for FCoE
packets which use the SAN MTU and FCoE offloads.
We resolve this regression by fixing ixgbe_copy_dcb_cfg() to also
check for FCoE application changes. Additionally, we can drop the
IEEE variants of get_dcb_app() because this path is never called
with the IEEE mode enabled.
