[PATCH net] ice: fix ice_init_link() error return preventing probe

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

From: Paul Greenwalt <paul.greenwalt@intel.com>

ice_init_link() can return an error status from ice_update_link_info()
or ice_init_phy_user_cfg(), causing probe to fail.

An incorrect NVM update procedure can result in link/PHY errors, and
the recommended resolution is to update the NVM using the correct
procedure. If the driver fails probe due to link errors, the user
cannot update the NVM to recover. The link/PHY errors logged are
non-fatal: they are already annotated as 'not a fatal error if this
fails'.

Since none of the errors inside ice_init_link() should prevent probe
from completing, convert it to void and remove the error check in the
caller. All failures are already logged; callers have no meaningful
recovery path for link init errors.

Fixes: 5b246e533d01 ("ice: split probe into smaller functions")
