JDK-8328776: [AIX] remove checked_vmgetinfo, use vmgetinfo directly

[MBaesken]

The subroutine vmgetinfo
https://www.ibm.com/docs/es/aix/7.2?topic=v-vmgetinfo-subroutine
https://www.ibm.com/docs/es/aix/7.1?topic=v-vmgetinfo-subroutine
was not available on very old OS releases; but we do not support / run on those old releases anyway these days so the helper checked_vmgetinfo can be removed.

LGTM. BTW, I guess we can remove every occurence of os::Aix::on_pase() to cleanup the code.

[RealLucy]
