tipc: recode getsockopt error handling for better readability
The existing code for the copy to user and error handling at the end of getsockopt isn't easy to follow, due to the excessive use of if/else. By simply using return where appropriate, it can be made smaller and easier to follow at the same time. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S.
