Summary

acct_process() resets the resource limits in exiting process, mostly to
ensure that a file size limit does not inhibit writing to the accounting
record file configured with acct(2). But since we started caching
limits in threads, we need to reset that pointer too.

Noticed while investigating a syzkaller bug.

I dislike this hack with replacing p_limit/td_limit. We have the file size limit check done in vn_file_size(), so it is easy to avoid the limit check when not needed. Please see D30257
