[PATCH] header: add possible_{write,read}_pnet() on kernel >= 4.1

[Hauke Mehrtens]

backports only adds the possible_{write,read}_pnet() functions for
kernel < 4.1. This results in a compile error on kernel 4.1. This patch
make it use the original functions on these kernel versions. This fixes
a problem introduced in 3d418885971.
