sbitmap: remove unnecessary calculation of alloc_hint in __sbitmap_get_shallow
[ Upstream commit f1591a8bb3e02713f4ee2efe20df0d84ed80da48 ]
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.
