xfrm: remove irrelevant comment in xfrm_input().

ramirosen · klassert · commit e3fec5a1c5a1 · 2013-08-19T12:45:16.000+02:00
This patch removes a comment in xfrm_input() which became irrelevant
due to commit 2774c13, "xfrm: Handle blackhole route creation via afinfo".
That commit removed returning -EREMOTE in the xfrm_lookup() method when the
packet should be discarded  and also removed the correspoinding -EREMOTE
handlers. This was replaced by calling the make_blackhole() method. Therefore
the comment about -EREMOTE is not relevant anymore.
