mm/memory.c: mark create_huge_pmd() inline to prevent build failure

With gcc 4.1.2:

    mm/memory.o: In function `create_huge_pmd':
    memory.c:(.text+0x93e): undefined reference to `do_huge_pmd_anonymous_page'

Interestingly, create_huge_pmd() is emitted in the assembler output, but
never called.

Converting transparent_hugepage_enabled() from a macro to a static
inline function reduced the ability of the compiler to remove unused
code.

Fix this by marking create_huge_pmd() inline.
