ACPI / debugger: Fix regression introduced by IS_ERR_VALUE() removal
 
The FIFO unlocking mechanism in acpi_dbg has been broken by the
following commit:

  Commit: 287980e49ffc0f6d911601e7e352a812ed27768e
  Subject: remove lots of IS_ERR_VALUE abuses

It converted !IS_ERR_VALUE(ret) into !ret which was not entirely
correct. Fix the regression by taking ret > 0 into account too as
appropriate.

Fixes: 287980e49ffc (remove lots of IS_ERR_VALUE abuses)
