zpool import -m also removing spare and cache when log device is missing

Browse Source 
spa_import() relies on a pool config fetched by spa_try_import() for
spare/cache devices. Import flags are not passed to spa_tryimport(),
which makes it return early due to a missing log device and missing
retrieving the cache device and spare eventually. Passing
ZFS_IMPORT_MISSING_LOG to spa_tryimport() makes it fetch the correct
configuration regardless of the missing log device.
