Subject: net/smc: allow unprivileged users to read pnet table
Git-commit: 29237d22bc45d340792be217f40fb728ca48b6e6
Patch-mainline: v5.6-rc1
References: jsc#SLE-13763

The current flags of the SMC_PNET_GET command only allow privileged
users to retrieve entries from the pnet table via netlink. The content
of the pnet table may be useful for all users though, e.g., for
debugging smc connection problems.

This patch removes the GENL_ADMIN_PERM flag so that unprivileged users
can read the pnet table.
