Move the fifo engine activity disabling and wait-for-idle from the lowest-level functions higher, into the ioctl path of zbc operations, so that the sw initialization path wouldn't call them. During the init path, the disable isn't necessary, and the code path could result in a deadlock in the fifo runlist mutex.
