[PATCH] scsi: qla2xxx: Fix wrong return value in qlt_chk_unresolv_exchg()

[Tianjia Zhang]

In the case of a failed retry, a positive value EIO is returned here.
I think this is a typo error. It is necessary to return an error value.

Fixes: 0691094ff3f2c ("scsi: qla2xxx: Add logic to detect ABTS hang and 
response completion")
