efi: Use a file local lock for efivars
This patch replaces the spinlock in the efivars struct with a single lock for the whole vars.c file. The goal of this lock is to protect concurrent calls to efi variable services, registering and unregistering. This allows us to register new efivars operations without having in-progress call.
