gpu: nvgpu: Initialize is_sl_supported to false
...
We want to support 1/8th mode only if both endpoints have enabled
it. To know if each endpt supports 1/8th mode in the core driver,
we added a new field in shared nvlink_link struct.
Initialize this new field to false as dGPU nvlink does not currently
support 1/8th mode.
