genetlink: Fix uninitialized variable in genl_validate_assign_mc_groups()
net/netlink/genetlink.c: In function ‘genl_validate_assign_mc_groups’:
net/netlink/genetlink.c:217: warning: ‘err’ may be used uninitialized in this
function
Commit 2a94fe48f3
("genetlink: make multicast
groups const, prevent abuse") split genl_register_mc_group() in multiple
functions, but dropped the initialization of err.
Initialize err to zero to fix this.
