tipc: remove redundant assignment to ret, simplify code 

Variable err is being assigned a zero value and it is never read
afterwards in either the break path or continue path, the assignment
is redundant and can be removed. With it removed, the if statement
can also be simplified.

Cleans up clang scan warning:
net/tipc/socket.c:3570:5: warning: Value stored to 'err' is never
read [deadcode.DeadStores]
