Merge branch 'net-redundant-judgments'

Li Zetao says:

====================
net: Delete some redundant judgments

This patchset aims to remove some unnecessary judgments and make the
code more concise. In some network modules, rtnl_set_sk_err is used to
record error information, but the err is repeatedly judged to be less
than 0 on the error path. Deleted these redundant judgments.

No functional change intended.
