[PATCH 03/11] kselftest/arm64: Move exit calls out of fp-stress loads

[Mark Brown]

When they detect corruption the fp-stress test loads print load specific
diagnostics and exits with a failure status.  In preparation for
building versions intended to run as KVM guests factor the exits into
asm-utils-linux.S.

No functional change.
