soc: qcom: pdr: Remove impossible error condition

The patch fbe639b4: "soc: qcom: Introduce Protection Domain
Restart helpers" leads to the following static checker warning:

drivers/soc/qcom/pdr_interface.c:158 pdr_register_listener()
'(resp.curr_state < (-((~0 >> 1)) - 1)) => (s32min-s32max < s32min)'
These are casted to int so they can't be outside of int range.
