We currently fail the transfer when issuing more than 255 transactions
at once, e.g.
> read_memory 0x10000000 32 256
CMSIS-DAP transfer count mismatch: expected 257, got 1
This is because the protocol only supports 255 transactions per packet
(65535 for block transactions), and as a result we truncate the
transaction count when assembling the packet. Fix it by running the
queue when we hit the limit.
