x86, paravirt: fix build error when thp is disabled
With CONFIG_PARAVIRT=y and CONFIG_TRANSPARENT_HUGEPAGE=n, the build breaks
because set_pmd_at() is undeclared:
mm/memory.c: In function 'do_pmd_numa_page':
mm/memory.c:3520: error: implicit declaration of function 'set_pmd_at'
mm/mprotect.c: In function 'change_pmd_protnuma':
mm/mprotect.c:120: error: implicit declaration of function 'set_pmd_at'
This is because paravirt defines set_pmd_at() only when
CONFIG_TRANSPARENT_HUGEPAGE=y and such a restriction is unneeded. The
fix is to define it for all CONFIG_PARAVIRT configurations.
