ACPI: MRRM: Silence error code static checker warning

Browse source 
The error code is not set correctly on if kasprintf() fails.  On the
first iteration it would return -EINVAL and subsequent iterations
would return success.  Set it to -ENOMEM.

In real life, this allocation will not fail and if it did the system
will not boot so this change is mostly to silence static checker warnings
more than anything else.
