ACPI: APEI: EINJ: Fix check and iounmap of uninitialized pointer p
In the case where a request_mem_region call fails and pointer r is null
the error exit path via label 'out' will check for a non-null pointer
p and try to iounmap it. However, pointer p has not been assigned a
value at this point, so it may potentially contain any garbage value.
Fix this by ensuring pointer p is initialized to NULL.
