sbitmap: remove unnecessary calculation of alloc_hint in __sbitmap_get_shallow

Browse source

Updates to alloc_hint in the loop in __sbitmap_get_shallow() are mostly
pointless and equivalent to setting alloc_hint to zero (because
SB_NR_TO_BIT() considers only low sb->shift bits from alloc_hint). So
simplify the logic.
