subpage_prot.2: SYNOPSIS: Fix return type: s/long/int/ 

The Linux kernel uses 'int' instead of 'long' for the return type.
As glibc provides no wrapper, use the same type the kernel uses.

......

$ grep -n wrapper man-pages/man2/subpage_prot.2
40:There is no glibc wrapper for this system call; see NOTES.
99:Glibc does not provide a wrapper for this system call; call it using

$ grep -rn SYSCALL_DEFINE.*subpage_prot linux/;

SYSCALL_DEFINE3(subpage_prot, unsigned long, addr,
