fcoe: Allow more time for the bnx2x link negotiation before brining up fcoe interfaces.

bnx2x can take no longer than 3 seconds to initialize the link in some setups
which can cause fipvlan to fail and thus the fcoe interface(s) won't be
created.

Add another 10 seconds to give the link enough time to initialize.
