[SCSI] qla2xxx: fix regression on sparc64
Some sparc64 boxes don't have a valid NVRAM (from which the driver takes its WWPN) try to extract this from open firmware instead and if that fails, fall back to a default, which would be invalid if more than one machine on the same SAN does this, since two machines with the same WWPN would be illegal, so warn when taking this potentially invalid default. Tested on SunBlade-1000: Acked-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
