can: netns: give members of struct netns_can holding the statistics a sensible name

This patch gives the members of the struct netns_can that are holding
the statistics a sensible name, by renaming struct netns_can::can_stats
into struct netns_can::pkg_stats and struct netns_can::can_pstats into
struct netns_can::rcv_lists_stats.

The conversion is done with:

	sed -i \
		-e "s:\(struct[^*]*\*\)can_stats;.*:\1pkg_stats;:" \
		-e "s:\(struct[^*]*\*\)can_pstats;.*:\1rcv_lists_stats;:" \
		-e "s/can\.can_stats/can.pkg_stats/g" \
		-e "s/can\.can_pstats/can.rcv_lists_stats/g" \
		net/can/*.[ch] \
