ACPI: APEI: fix the wrong iteration of generic error status block

Browse Source 
The revision 0x300 generic error data entry is different
from the old version, but currently iterating through the
GHES estatus blocks does not take into account this difference.
This will lead to failure to get the right data entry if GHES
has revision 0x300 error data entry.

Update the GHES estatus iteration macro to properly increment using
acpi_hest_get_next(), and correct the iteration termination condition
because the status block data length only includes error data
length.

Convert the CPER estatus checking and printing iteration logic
to use same macro.
