ice: remove comment about not supporting driver reinit

Since commit 31c8db2c4fa7 ("ice: implement devlink reinit action"), the ice
driver does support driver re-initialization via devlink reload. Remove the
stale comment indicating that the driver lacks this support from the
ice_devlink_ops structure.
