[PATCH 5/8] arch/loongarch: Stop special-casing hugetlb in arch_get_unmapped_area_common

[Oscar Salvador]

arch_get_unmapped_* sets info.align_mask to make room for extra alignment,
so that is added on top of the length we request in unmapped_area{_topdown}.
hugetlb_get_unmapped_area() already adds this extra padding in the 'len'
parameter, and it masks off the address it gets to properly align it to
the huge_page_size we are using.

Stop special-casing hugetlb in arch_get_unmapped_area_common.
The only caveat is that we might get extra align_mask in case we do coloring,
but that should only make us allocate a larger(ish) gap in unmapped_area{_topdown}.
