History
Guillaume Nault 16a2826777 ipv4: Don't reset ->flowi4_scope in ip_rt_fix_tos(). 
All callers already initialise ->flowi4_scope with RT_SCOPE_UNIVERSE,
either by manual field assignment, memset(0) of the whole structure or
implicit structure initialisation of on-stack variables
(RT_SCOPE_UNIVERSE actually equals 0).

Therefore, we don't need to always initialise ->flowi4_scope in
ip_rt_fix_tos(). We only need to reduce the scope to RT_SCOPE_LINK when
the special RTO_ONLINK flag is present in the tos.

This will allow some code simplification, like removing
ip_rt_fix_tos(). Also, the long term idea is to remove RTO_ONLINK
entirely by properly initialising ->flowi4_scope, instead of
overloading ->flowi4_tos with a special flag. Eventually, this will
allow to convert ->flowi4_tos to dscp_t.
