block/crypto: create ciphers on demand
Ciphers are pre-allocated by qcrypto_block_init_cipher() depending on the given number of threads. The -device virtio-blk-pci,iothread-vq-mapping= feature allows users to assign multiple IOThreads to a virtio-blk device, but the association between the virtio-blk device and the block driver happens after the block driver is already open. When the number of threads given to qcrypto_block_init_cipher() is smaller than the actual number of threads at runtime, the block->n_free_ciphers > 0 assertion in qcrypto_block_pop_cipher() can fail. Get rid of qcrypto_block_init_cipher() n_thread's argument and allocate ciphers on demand.
