ACPI: thermal_lib: Initialize temp_decik to zero
Static analysis with clang scan build is warning that uninitialized
data is being passed into various functions. Stop these warnings by
initializing temp_decik to zero.
Cleans up clang scan warnings in lines 106, 125, 146 and 164 such as:
drivers/acpi/thermal_lib.c:106:9: warning: 2nd function call argument
is an uninitialized value [core.CallAndMessage]
Kudos to Dan Carpenter for the deeper analysis of this issue.
