Subject: [PATCH 4.13 070/109] scsi: qla2xxx: Use BIT_6 to acquire FAWWPN from switch

4.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sawan Chandak <sawan.chandak@...ium.com>

commit fcc5b5cd726c0779cd689362aea82cc9d5a61346 upstream.

If FA-WWPN feature disabled on the switch side and enabled for the
adapter, then driver would update the port name with switch port name.

This patch fixes issue by checking correct BIT flag to validate.
