kernel/acct.c: use dedicated helper to access rlimit values

Browse source 
[ Upstream commit 3c91dda97eea704ac257ddb138d1154adab8db62 ]

Use rlimit() helper instead of manually writing whole chain from
task to rlimit value. See patch "posix-cpu-timers: Use dedicated
helper to access rlimit values".
