crypto: cavium/nitrox - Fix 'nitrox_get_first_device()' when ndevlist is fully iterated
When a list is completely iterated with 'list_for_each_entry(x, ...)', x is not NULL at the end. While at it, remove a useless initialization of the ndev variable. It is overridden by 'list_for_each_entry'. Fixes: f2663872f073 ("crypto: cavium - Register the CNN55XX supported crypto algorithms.")
