[PATCH] scsi: qlogicpti: Fix an error handling path in 'qpti_sbus_probe()'

[Christophe JAILLET]

The 'free_irq()' call is not at the right place in the error handling path.
The changed order has been introduced in commit 3d4253d9afab
("[SCSI] qlogicpti: Convert to new SBUS device framework.")

Please review carefully.  This patch is proposed because it triggers one of
my coccinelle scripts. I'm not 100% sure if correct.

The script tries to spot wrongly ordered error handling path. It is:
@@
identifier l1, l2;
@@

  if (...) {
     ...
*     goto l1;
  }
  ...
  if (...) {
     ...
*     goto l2;
  }
  ...
*l1:
  ...
*l2:
