[PATCH v4 18/22] net: fix IPv4 macro with highest bit

[David Marchand]

Without an explicit type, all parameters of this macro are considered as
a signed integer.

../app/test/test_fib.c:270:20: runtime error: left shift of
	128 by 24 places cannot be represented in type 'int'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
	../app/test/test_fib.c:270:20 in
