Subject: ACPI: APEI: Put the error injection table for error path and module
exit
Patch-mainline: v5.8-rc1
Git-commit: 541156a38fd01d9c01b24065bd6f361b9911be12
References: jsc#SLE-16407
The mapped error injection table will be used after einj_init()
for debugfs, but it should be released for module exit and error
path of einj_init().
