Colin Ian King bf18fd89f9 void integer overflow on computation of refquota_slack 
DMU_MAX_ACCESS should be cast to a uint64_t otherwise the
multiplication of DMU_MAX_ACCESS with spa_asize_inflation will
be 32 bit and may lead to an overflow. Currently DMU_MAX_ACCESS
is 64 * 1024 * 1024, so spa_asize_inflation being 64 or more will
lead to an overflow.

Found by static analysis with CoverityScan 0.8.5

CID 150942 (#1 of 1): Unintentional integer overflow
  (OVERFLOW_BEFORE_WIDEN)
overflow_before_widen: Potentially overflowing expression
  67108864 * spa_asize_inflation with type int (32 bits, signed)
  is evaluated using 32-bit arithmetic, and then used in a context
  that expects an expression of type uint64_t (64 bits, unsigned).
