ice: move ice_deinit_dev() to the end of deinit paths

ice_deinit_dev() takes care of turning off adminq processing, which is
much needed during driver teardown (remove, reset, error path). Move it
to the very end where applicable.
For example, ice_deinit_hw() called after adminq deinit slows rmmod on
my two-card setup by about 60 seconds.

ice_init_dev() and ice_deinit_dev() scopes were reduced by previous
commits of the series, with a final touch of extracting ice_init_dev_hw()
out now (there is no deinit counterpart).

Note that removed ice_service_task_stop() call from ice_remove() is placed
in the ice_deinit_dev() (and stopping twice makes no sense).
