MDEV-31475 remove unnecessary assignment to spider share init_error

The init, init_error, and init_error_time fields of a SPIDER_SHARE
should only be assigned when actually doing the initialisation of a
SPIDER_SHARE, otherwise they could result in spurious failures from
spider_get_share() in a subsequent statement.
