xfrm: use "unsigned int" in addr_match()
x86_64 is zero-extending arch so "unsigned int" is preferred over "int"
for address calculations and extending to size_t.
Space savings:
add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-24 (-24)
function old new delta
xfrm_state_walk 708 696 -12
xfrm_selector_match 918 906 -12
