net: pfcp: allocate per-cpu tstats for PFCP netdevs
PFCP uses dev_get_tstats64() as its ndo_get_stats64 callback, but
pfcp_link_setup() does not request NETDEV_PCPU_STAT_TSTATS. The net
core therefore leaves dev->tstats NULL for PFCP devices.
Creating a PFCP rtnetlink device can immediately ask the new netdev for
stats while building the RTM_NEWLINK notification. That reaches
dev_get_tstats64() and dereferences the NULL dev->tstats pointer.
Set pcpu_stat_type to NETDEV_PCPU_STAT_TSTATS during PFCP link setup so
the net core allocates the storage expected by dev_get_tstats64().
