ice: fix infinite recursion in ice_cfg_tx_topo via ice_init_dev_hw

On certain E810 configurations where firmware supports Tx scheduler
topology switching (tx_sched_topo_comp_mode_en), ice_cfg_tx_topo()
may need to apply a new 5-layer or 9-layer topology from the DDP
package. If the AQ command to set the topology fails (e.g. due to
invalid DDP data or firmware limitations), the global configuration
lock must still be cleared via a CORER reset.

Commit 86aae43f21cf ("ice: don't leave device non-functional if Tx
scheduler config fails") correctly fixed this by refactoring
ice_cfg_tx_topo() to always trigger CORER after acquiring the global
lock and re-initialize hardware via ice_init_hw() afterwards.

However, commit 8a37f9e2ff40 ("ice: move ice_deinit_dev() to the end
of deinit paths") later moved ice_init_dev_hw() into ice_init_hw(),
breaking the reinit path introduced by 86aae43f21cf. This creates an
infinite recursive call chain:

  ice_init_hw()
    ice_init_dev_hw()
      ice_cfg_tx_topo()         # topology change needed
        ice_deinit_hw()
        ice_init_hw()           # reinit after CORER
          ice_init_dev_hw()     # recurse
            ice_cfg_tx_topo()
              ...               # stack overflow

Fix by moving ice_init_dev_hw() back out of ice_init_hw() and calling
it explicitly from ice_probe() and ice_devlink_reinit_up(). The third
caller, ice_cfg_tx_topo(), intentionally does not need ice_init_dev_hw()
during its reinit, it only needs the core HW reinitialization. This
breaks the recursion cleanly without adding flags or guards.

The deinit ordering changes from commit 8a37f9e2ff40 ("ice: move
ice_deinit_dev() to the end of deinit paths") which fixed slow rmmod
are preserved, only the init-side placement of ice_init_dev_hw() is
reverted.
