ravb: kill redundant check in the probe() method

Sergei Shtylyov · davem330 · commit 5d0c100c228b · 2018-01-03T10:21:35.000-05:00
Browsing thru the driver disassembly, I noticed that gcc was  able to
figure  out  that the 'ndev' pointer is always non-NULL when calling
free_netdev()  on the probe() method's  error path and  thus skip that
redundant NULL check... gcc is smart, be like gcc! :-)
