modify_prefix_route() is given the lifetime in clock_t relative to now,
but fib6_set_expires() wants an absolute jiffies value. So when a
permanent address is changed to a finite valid_lft, the prefix route
ends up already expired and GC removes it.
Steps to reproduce:
ip link add dummy9 type dummy
ip link set dummy9 up
ip -6 addr add 2001:db8:9::1/64 dev dummy9
ip -6 addr change 2001:db8:9::1/64 dev dummy9 valid_lft 3600 preferred_lft 3600
ip -6 route show dev dummy9 # expires is negative
