[PATCH 2/3] sgi-gru: Remove CONFIG_HUGETLB_PAGE ifdef

[Bharath Vedartham]

is_vm_hugetlb_page has checks for whether CONFIG_HUGETLB_PAGE is defined
or not. If CONFIG_HUGETLB_PAGE is not defined is_vm_hugetlb_page will
always return false. There is no need to have an uneccessary
CONFIG_HUGETLB_PAGE check in the code.
