If kip->nused is not zero, collect_one_slot() return false, otherwise do
a lot of linked list operations, reverse the processing order to make the
code if nesting more concise. __disable_kprobe() is the same as well.

The CONFIG_KPROBES_ON_FTRACE #if/#else/#endif section is small and doesn't
nest additional #ifdefs so the comment is useless and should be removed,
but the __ARCH_WANT_KPROBES_INSN_SLOT and CONFIG_OPTPROBES() nest is long,
it is better to add comment for reading.

Add the __counted_by compiler attribute to the flexible array member
stripes to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and
CONFIG_FORTIFY_SOURCE.

ight.
"DRDTIME" can access independent stable counter of the processor core
according to "Loongson Processor 3C5000L Register Instruction Manual",
which is similar to "RDTSC" in x86.
I'll update it in next version.
