[PATCH 04/11] kselftest/arm64: Use exit_error() rather than SIGABRT in fp-stress

[Mark Brown]

The fp-stress test loads all deliver a SIGABRT to the process group to
report some errors they detect. There is no particular reason to use
this mechanism over exiting with an error code, the fp-stress harness does
not care. In order to facilitate running as KVM guests replace this with
use of the exit_error() function we added.
