vhost_user_block: Use struct instantiation rather than mut variable

Browse Source 
error: field assignment outside of initializer for an instance created with Default::default()
   --> vhost_user_block/src/lib.rs:223:9
    |
223 |         config.capacity = nsectors;
    |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^
    |
    = note: `-D clippy::field-reassign-with-default` implied by `-D warnings`
note: consider initializing the variable with `block_util::VirtioBlockConfig { capacity: nsectors, blk_size: BLK_SIZE, size_max: 65535, seg_max: 128 - 2, min_io_size: 1, opt_io_size: 1, num_queues: num_queues as u16, writeback: 1, ..Default::default() }` and removing relevant reassignments

221 |         let mut config = VirtioBlockConfig::default();
