Merge patch series "scsi: qla2xxx: Fix incorrect sign of error code"

Qianfeng Rong <rongqianfeng@vivo.com> says:

qla2x00_start_sp() returns only negative error codes or QLA_SUCCESS.
Therefore, comparing its return value with positive error codes (e.g.,
if (_rval == EAGAIN)) causes logical errors.
