__ll_vmalloc() -> __compat_vmalloc()

missing semi-colon after:
ENUM2STR(GNI_RC_SUCCESS)

GNI needs to include:

Build fix: -Werror=maybe-uninitialized

.../lustre/mgc/mgc_request.c: In function 'mgc_create_new_conn':
.../include/linux/libcfs/libcfs_debug.h:122:3: error: 'rc' may be \
used uninitialized in this function [-Werror=maybe-uninitialized]
