afs: alloc openafs_lck_grp before osi_Init() on darwin

Commit a27bed59cae1a4244429c752edfde0a8363c8a3b moved init_hckernel_init
to osi_Init. On Darwin (AFS_DARWIN80_ENV), MUTEX_INIT
(called by init_hckernel_init) uses openafs_lck_grp as the argument of
one of the functions called during the initialization of the mutex in
question. Since openafs_lck_grp was not allocated yet, we crash.

To fix this problem, call MUTEX_SETUP() before osi_Init() on Darwin.
