When CONFIG_SYSCTL=n and CONFIG_BINFMT_MISC={y,m}, compiler will
complain due to return type not matching. Fix the return type in
register_sysctl_mount_point() to make compiler happy
fs/binfmt_misc.c: In function ‘init_misc_binfmt’:
fs/binfmt_misc.c:827:21: error: assignment to ‘struct ctl_table_header *’ from incompatible pointer type ‘struct sysctl_header *’ [-Werror=incompatible-pointer-types]
827 | binfmt_misc_header = register_sysctl_mount_point("fs/binfmt_misc");
Fixes: ee9efac48a08("sysctl: add helper to register a sysctl mount point")
