share_pool: change printk_ratelimit to pr_level_ratelimited

ascend inclusion
category: perf
bugzilla: https://gitee.com/openeuler/kernel/issues/I4EUVI
CVE: NA

-------------------------------------------------
According to kernel comment, printk_ratelimited is not recommended, we
should use pr_<level>_ratelimited instead.

This also helps to reduce cyclomatic complexity.

In addition, %pK is not useful when we want to know the virtual memory
address. We decide to use pr_debug() and %lx, only root users have the
permission to switch /sys/kernel/debug/dynamic_debug/control which meets
the security requirements.
