net: sctp: migrate cookie life from timeval to ktime
Currently, SCTP code defines its own timeval functions (since timeval is rarely used inside the kernel by others), namely tv_lt() and TIMEVAL_ADD() macros, that operate on SCTP cookie expiration. We might as well remove all those, and operate directly on ktime structures for a couple of reasons: ktime is available on all archs; complexity of ktime calculations depending on the arch is less than (reduces to a simple arithmetic operations on archs with BITS_PER_LONG == 64 or CONFIG_KTIME_SCALAR) or equal to timeval functions (other archs); code becomes more readable; macros can be thrown out.
