[BUGFIX 0/2] ACPI, APEI, Fix two bugs of APEI implementation

[Huang Ying]

Fix two bugs of APEI implementaiton.

[BUGFIX 1/2] ACPI, APEI, Fix a typo of error path of apei_resources_request
[BUGFIX 2/2] ACPI, APEI, Rename CPER and GHES severity constants

[BUGFIX 1/2] ACPI, APEI, Fix a typo of error path of apei_resources_request

[Huang Ying]

Fix a typo of error path of apei_resources_request. release_mem_region
and release_region should be interchange.

[BUGFIX 2/2] ACPI, APEI, Rename CPER and GHES severity constants

[Huang Ying]

The abbreviation of severity should be SEV instead of SER, so the CPER
severity constants are renamed accordingly. GHES severity constants
are renamed in the same way too.
