netfs: silence an uninitialized variable warning

Browse Source 
Smatch complains that "ret" is uninitialized on the success path if we
don't enter the nested loop at the end of the function.  In real life we
will enter that loop so "ret" will be zero.

Generally, I don't endorse silencing static checker warnings but in this
case, I think it make sense.
