gpu: nvgpu: remove max_ctxsw_ring_buffer_size from nvgpu_gr

Browse Source 
max_ctxsw_ring_buffer_size variable in struct nvgpu_gr is used to store
max ring buffer size which is then referred into linux specific code

We only use macro GK20A_CTXSW_TRACE_MAX_VM_RING_SIZE to initialize
the variable.

And max_ctxsw_ring_buffer_size does not belong to nvgpu_gr struct
anyways

Considering above remove max_ctxsw_ring_buffer_size from nvgpu_gr and
use macro directly in linux specific code
