[PATCH 08/29] qla2xxx: Return blank sysfs string on initial get thermal failure.

[Chad Dupuis <chad.dupuis@xxxxxxxxxx>]

From: Joe Carnuccio <joe.carnuccio@xxxxxxxxxx>

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.
