interconnect: qcom: rpm: allocate enough data in probe()

This was not allocating enough bytes.  There are two issue here.
First, there was a typo where it was taking the size of the pointer
instead of the size of the struct, "sizeof(qp->intf_clks)" vs
"sizeof(*qp->intf_clks)".  Second, it's an array of "cd_num" clocks so
we need to allocate space for more than one element.
