bpf, sysctl: Let bpf_stats_handler take a kernel pointer buffer
Commit 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")
changed ctl_table.proc_handler to take a kernel pointer. Adjust the
signature of bpf_stats_handler to match ctl_table.proc_handler which
fixes the following sparse warning:
kernel/sysctl.c:226:49: warning: incorrect type in argument 3 (different address spaces)
kernel/sysctl.c:226:49: expected void *
kernel/sysctl.c:226:49: got void [noderef] __user *buffer
kernel/sysctl.c:2640:35: warning: incorrect type in initializer (incompatible argument 3 (different address spaces))
kernel/sysctl.c:2640:35: expected int ( [usertype] *proc_handler )( ... )
kernel/sysctl.c:2640:35: got int ( * )( ... )
Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")
