video: tegra: host: fix disable_clk() sequence
nvhost_module_disable_clk() currently first disables the clocks
and then suspends the channels as follows :
clk_disable_unprepare()
nvhost_channel_suspend()
reverse this sequence as below and keep clock disabling after
the channel operations
nvhost_channel_suspend()
clk_disable_unprepare()
