scsi: qla2xxx: Initialized mailbox to prevent driver load failure
[ Upstream commit c2ff2a36eff60efb5e123c940115216d6bf65684 ]
This patch fixes issue with Gen7 adapter in a blade environment where one
of the ports will not be detected by driver. Firmware expects mailbox 11 to
be set or cleared by driver for newer ISP.
Following message is seen in the log file:
[ 18.810892] qla2xxx [0000:d8:00.0]-1820:1: **** Failed=102 mb[0]=4005 mb[1]=37 mb[2]=20 mb[3]=8
[ 18.819596] cmd=2 ****
[mkp: typos]
