ACPI / processor_thermal: avoid null pointer deference error
Fix a null pointer deference by acpi_driver_data() if device is
null. We should only set pr and check this is OK after we are
sure device is not null.
Smatch analysis:
drivers/acpi/processor_thermal.c:223 processor_get_max_state() warn:
variable dereferenced before check 'device' (see line 221)
drivers/acpi/processor_thermal.c:237 processor_get_cur_state() warn:
variable dereferenced before check 'device' (see line 235)
drivers/acpi/processor_thermal.c:255 processor_set_cur_state() warn:
variable dereferenced before check 'device' (see line 251)
