Subject: [PATCH] x86/mm: fix compilation error for unknown type name pgprot_t

commit 30796e18c299 ("x86/mm: introduce __set_memory_prot()")
added the function __set_memory_prot() which uses pgprot_t in
function prototype. The currently included header files in
<arch/x86/include/asm/set_memory.h> do not include type name
pgprot_t. The pgprot_t is defined in <asm/pgtable_types.h>.

Fixes: 30796e18c299 ("x86/mm: introduce __set_memory_prot()")
