Sudip Mukherjee ea78361174 thermal/drivers/ti-soc-thermal: Avoid dereferencing ERR_PTR 
[ Upstream commit 7440f518da ]

On error the function ti_bandgap_get_sensor_data() returns the error
code in ERR_PTR() but we only checked if the return value is NULL or
not. And, so we can dereference an error code inside ERR_PTR.
While at it, convert a check to IS_ERR_OR_NULL.
