gpu: nvgpu: skip taking g->busy_lock in gk20a_idle
We use g->busy_lock in gk20a_do_idle() to prevent submitting
more jobs to h/w and to wait for currently running jobs to
finish
But requesting this lock in gk20a_idle() prevents decrementing
runtime counter and hence gk20a_do_idle() can timeout with
below prints
[ 148.904739] gk20a 17000000.gp10b: Timeout detected @
gk20a_do_idle+0x30/0x38
[ 148.912185] gk20a 17000000.gp10b: __gk20a_do_idle: failed to idle -
refcount 4 != 1
Hence skip requesting this lock in gk20a_idle()
