Deepak Nibade a969bc98ae gpu: nvgpu: remove gk20a_busy() from channel_syncpt_update() ...

gk20a_busy() was added to gk20a_channel_syncpt_update() for possible
case of channel deletion

But API to delete a channel (i.e. gk20a_free_channel()) is already
called in paths which ensure gk20a_busy() is called before
deleting the channel

Hence, remove redundant gk20a_busy()/idle() calls

This also fixes a deadlock scenario with VPR resize use case
