With this patch, it does not change the current limit, MAX_TAIL_CALL_CNT
can reflect the actual max tail call count, and the above failed testcase
can be fixed.

x count reached jited:1 ret 34 != 33 FAIL
with this patch, make the actual max tail call count as MAX_TAIL_CALL_CNT,
at the same time, the above failed testcase can be fixed.

In arch/*/kernel/crash_dump*.c, there exist many similar code
about copy_oldmem_page(), remove copy_to() in fs/proc/vmcore.c
and add copy_to_user_or_kernel() in lib/usercopy.c, then we can
use copy_to_user_or_kernel() to simplify the related code.
