Bluetooth: hci_sync: Use cmd->num_cis instead of magic number
At the moment of the check, `cmd->num_cis` holds the value of 0x1f,
which is the max number of elements in the `cmd->cis[]` array at
declaration, which is 0x1f.
So, avoid using 0x1f directly, and instead use `cmd->num_cis`. Similarly
to this other patch[1].
