s390: remove is_32bit_task() helper
is_32bit_task() used to be helpful when we still had CONFIG_32BIT. Since that is gone, it is nowadays identical to is_compat_task(). So remove it. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
