"lbas" with type "u16" (16 bits, unsigned) is promoted in "lbas << ns->lba_shift" to type "int" (32 bits, signed), then sign-extended to type "unsigned long long" (64 bits, unsigned). If "lbas << ns->lba_shift" is greater than 0x7FFFFFFF, the upper bits of the result will all be 1. Fix it by casting "lbas" to "u32".
