net: socket: move ktime2ts to ktime header api
Currently, ktime2ts is a small helper function that is only used in net/socket.c. Move this helper into the ktime API as a small inline function, so that i) it's maintained together with ktime routines, and ii) also other files can make use of it. The function is named ktime_to_timespec_cond() and placed into the generic part of ktime, since we internally make use of ktime_to_timespec(). ktime_to_timespec() itself does not check the ktime variable for zero, hence, we name this function ktime_to_timespec_cond() for only a conditional conversion, and adapt its users to it.
