gpu: nvgpu: zbc: disable activity only from ioctl
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.
