mei: fix up uuid matching 

A previous commit, c93b76b34b ("mei: bus: report also uuid in module
alias") caused a build error as I missed applying a needed patch to add
some macros to uapi/linux/uuid.h.  Instead of those additional macros,
change the mei code to use the existing uuid structure directly.

Fixes: c93b76b34b
