On line 428 pr->num_zones = powercap_ops->num_domains_get(), the return
of num_domains_get() is int, it can be a negative error code, however
this is being assigned to an unsigned int variable, so make the num_zones
to int to solve this problem without affecting other functions.
Eliminate the following coccicheck warning:
./drivers/powercap/arm_scmi_powercap.c:429:5-18: WARNING: Unsigned expression compared with zero: pr -> num_zones < 0
