Subject: [patch] enic: cleanup vic_provinfo_alloc()

If oui were a null variable then vic_provinfo_alloc() would leak memory.
But this function is only called from one place and oui is not null so 
I removed the check.

I also moved the memory allocation down a line so it was easier to spot.
(No one ever reads variable declarations).
