timekeeping: Remove __current_kernel_time()

The __current_kernel_time() function based on 'struct timespec' is no
longer recommended for new code, and the only user of this function has
been replaced by commit 6909e29fdefb ("kdb: use __ktime_get_real_seconds
instead of __current_kernel_time").

Remove the obsolete interface.
