MAINTAINERS: Fix Florian Fainelli's email address

Commit 31345a0 ("MAINTAINERS: Replace my email address") added 13
instances of [email protected] and one of only ...@Broadcom. I didn't
double check if Broadcom really owns that TLD, but git send-email
doesn't accept it, so add ".com" to that one bogous(?) instance.
