thermal: armada: fix legacy validity test sense

[ Upstream commit 70bb27b79adf63ea39e37371d09c823c7a8f93ce ]

Commit 8c0e64ac4075 ("thermal: armada: get rid of the ->is_valid()
pointer") removed the unnecessary indirection through a function
pointer, but in doing so, also removed the negation operator too:

-       if (priv->data->is_valid && !priv->data->is_valid(priv)) {
+       if (armada_is_valid(priv)) {

which results in:

armada_thermal f06f808c.thermal: Temperature sensor reading not valid
armada_thermal f2400078.thermal: Temperature sensor reading not valid
armada_thermal f4400078.thermal: Temperature sensor reading not valid

at boot, or whenever the "temp" sysfs file is read.  Replace the
negation operator.
