ACPI: APEI: Fix ERST timeout unit conversion
The ACPI specification defines bits 63:32 returned by
GET_EXECUTE_OPERATION_TIMINGS as the maximum execution time in
microseconds. erst_get_timeout() instead multiplies the value by
NSEC_PER_MSEC.
Use NSEC_PER_USEC to express the firmware-provided microsecond timeout
in the nanosecond units expected by erst_timedout().
Fixes: fac475aab70b ("ACPI: APEI: Use ERST timeout for slow devices")
