net: fix ip_mr_init() error path

Similarly to IPv6 ip6_mr_init() (fixed last week), the order of cleanup
operations in the error/exit section of ip_mr_init() is completely 
inversed. It should be the other way around.
Also a del_timer() is missing in the error path.

I should have guessed last week that this same error existed in ipmr.c
too, as ip6mr.c is largely inspired by ipmr.c.
