crypto: cavium/nitrox - Fix 'nitrox_get_first_device()' when ndevlist is fully iterated
commit 320bdbd816156f9ca07e5fed7bfb449f2908dda7 upstream.
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.")
