ACPI: APEI: fix return value of __setup handlers
__setup() handlers should return 1 to indicate that the boot option
has been handled. Returning 0 causes a boot option to be listed in
the Unknown kernel command line parameters and also added to init's
arg list (if no '=' sign) or environment list (if of the form 'a=b').
Unknown kernel command line parameters "erst_disable
bert_disable hest_disable BOOT_IMAGE=/boot/bzImage-517rc6", will be
passed to user space.
Run /sbin/init as init process
with arguments:
/sbin/init
erst_disable
bert_disable
hest_disable
with environment:
HOME=/
TERM=linux
BOOT_IMAGE=/boot/bzImage-517rc6

Fixes: a08f82d08053 ("ACPI, APEI, Error Record Serialization Table (ERST) support")
Fixes: 9dc966641677 ("ACPI, APEI, HEST table parsing")
