Switch allocations from KM_SLEEP to KM_PUSHPAGE
A couple of kmem_alloc() allocations were using KM_SLEEP in
the sync thread context. These were accidentally introduced
by the recent set of Illumos patches. The solution is to
switch to KM_PUSHPAGE.
dsl_dataset_promote_sync() -> promote_hold() -> snaplist_make() ->
kmem_alloc(sizeof (*snap), KM_SLEEP);
dsl_dataset_user_hold_sync() -> dsl_onexit_hold_cleanup() ->
kmem_alloc(sizeof (*ca), KM_SLEEP)
