Maciej Żenczykowski 4041f8c6b5 ipv6: fix ndisc_is_useropt() handling for PIO 
[ Upstream commit a46c68debf ]

The current logic only works if the PIO is between two
other ND user options.  This fixes it so that the PIO
can also be either before or after other ND user options
(for example the first or last option in the RA).

side note: there's actually Android tests verifying
a portion of the old broken behaviour, so:
  https://android-review.googlesource.com/c/kernel/tests/+/3196704
fixes those up.
