[PATCH net-next 3/3 v2] macsec: add brackets and indentation after calling macsec_decrypt

[PATCH net-next 3/3 v2] macsec: add brackets and indentation after calling macsec_decrypt

[Andreas Steinmetz]

At this point, skb could only be a valid pointer, so this patch does
not introduce any functional change.

Change:

The patch now only moves the IS_ERR(skb) case under the block where
macsec_decrypt() is called, but not the call to macsec_post_decrypt().
