scsi: qla2xxx: Skip unsupported sysfs attributes for 29xx

Browse Source 
Not all sysfs attributes are applicable to the 29xx adapter.  Return
-EPERM for attributes that are meaningless on 29xx (gold firmware
version, 84xx firmware version, flash block size, VLAN ID, VN-port MAC
address, and CNA firmware dump toggle) so that userspace tools do not
see stale or undefined values.
