bpf: Fix pointer cast warning

kp->addr is a pointer, so it cannot be cast directly to a 'u64'
when it gets interpreted as an integer value:

kernel/trace/bpf_trace.c: In function '____bpf_get_func_ip_kprobe':
kernel/trace/bpf_trace.c:968:21: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
  968 |         return kp ? (u64) kp->addr : 0;

Use the uintptr_t type instead.
