Fix recovery import (-F) with encrypted pool

Browse Source 
When performing zil_claim() at pool import time, it is
important that encrypted datasets set os_next_write_raw
before writing to the zil_header_t. This prevents the code
from attempting to re-authenticate the objset_phys_t when
it writes it out, which is unnecessary because the
zil_header_t is not protected by either objset MAC and
impossible since the keys aren't loaded yet. Unfortunately,
one of the code paths did not set this flag, which causes
failed ASSERTs during 'zpool import -F'. This patch corrects
this issue.
