powerpc/pseries: Return -EIO instead of -EINTR for H_ABORTED error

[ Upstream commit bb8e4c7cb759b90a04f2e94056b50288ff46a0ed ]

Some commands for eg. "cat" might continue to retry on encountering
EINTR. This is not expected for original error code H_ABORTED.

Map H_ABORTED to more relevant Linux error code EIO.
