ACPI: fan: fix unbalanced code block

The code block braced with CONFIG_ACPI_PROCFS is unblanced. When
CONFIG_ACPI_PROCFS=n, kernel trace will be produced like:

Call Trace:

---[ end trace a7919e7f17c0a725 ]---

Then also bracket later error checking code with ACPI_PROCFS
option to avoid mismatch problem.
