Change U16 to U32 due to atomic_inc_32_nv

After run a long time with QAT compression, the variable "inst_num" is overflow by "atomic_inc_32_nv", which causes its neighbor variable overwritten. Change its definition from U16 to U32. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Weigang Li <[email protected]> Closes #6051
