net: Move the permission check in sock_diag_put_filterinfo to packet_diag_dump
[ Upstream commit a53b72c83a4216f2eb883ed45a0cbce014b8e62d ]
The permission check in sock_diag_put_filterinfo is wrong, and it is so removed
from it's sources it is not clear why it is wrong. Move the computation
into packet_diag_dump and pass a bool of the result into sock_diag_filterinfo.
This does not yet correct the capability check but instead simply moves it to make
it clear what is going on.
