[SCSI] qla2xxx: Return blank sysfs string on initial get thermal failure.
When thermal temperature initially fails, return a blank string to the
sysfs interface. This fixes the initial display of 0.00 followed by
subsequent display of blank line; the initial 0.00 should have not
displayed for cards that do not support thermal temperature.
