      xfs: fix overflow in xfs_attr3_leaf_verify · 837514f7

      generic/070 on 64k block size filesystems is failing with a verifier
      corruption on writeback or an attribute leaf block:

      This is failing this check:
      
                      end = ichdr.freemap[i].base + ichdr.freemap[i].size;
                      if (end < ichdr.freemap[i].base)
      >>>>>                   return __this_address;
                      if (end > mp->m_attr_geo->blksize)
                              return __this_address;
      
      And from the buffer output above, the freemap array is:
      
      	freemap[0].base = 0x00a0
      	freemap[0].size = 0xdcf4	end = 0xdd94
      	freemap[1].base = 0xfe98
      	freemap[1].size = 0x0168	end = 0x10000
      	freemap[2].base = 0xf0d8
      	freemap[2].size = 0x07e0	end = 0xf8b8
      
      These all look valid - the block size is 0x10000 and so from the
      last check in the above verifier fragment we know that the end
      of freemap[1] is valid. The problem is that end is declared as:
      
      	uint16_t	end;
      
      And (uint16_t)0x10000 = 0. So we have a verifier bug here, not a
      corruption. Fix the verifier to use uint32_t types for the check and
      hence avoid the overflow.
