scsi: qla2xxx: Fix hang in fcport delete path
[ Upstream commit f00b3428a801758243693e046b34226e92bc56b3 ]
A hang was observed in the fcport delete path when the device was
responding slow and an issue-lip path (results in session termination) was
taken.
Fix this by issuing logo requests unconditionally.
