Tom Rix 6060a75e77 platform/x86: thinkpad_acpi: consistently check fan_get_status return.
Clang static analysis returns this false positive
thinkpad_acpi.c:8926:19: warning: The left operand
  of '!=' is a garbage value
  (status != 0) ? "enabled" : "disabled", status);
   ~~~~~~ ^

The return of fan_get_status* is checked inconsistenly.
Sometime ret < 0 is an error, sometimes !ret.
Both fan_get_status() and fan_get_status_safe() return
0 on success and return negative otherwise.  Change
the checks for error, ret < 0, into checks for
not success, !ret.
