efi: Fix the build with user namespaces enabled.

When compiling efivars.c the build fails with:

CC drivers/firmware/efivars.o
drivers/firmware/efivars.c: In function ‘efivarfs_get_inode’:
drivers/firmware/efivars.c:886:31: error: incompatible types when assigning to type ‘kgid_t’ from type ‘int’ make[2]: *** [drivers/firmware/efivars.o] Error 1
make[1]: *** [drivers/firmware/efivars.o] Error 2

Fix the build error by removing the duplicate initialization of i_uid and i_gid inode_init_always has already initialized them to 0.
